Types Of Mobility For Mobile Computing Computer Science Essay

Types Of Mobility For Mobile Computing Computer Science Essay The development in last 20 years in the field of telecommunication and the integration of telecommunication with internet has promised pervasive computing infrastructure. These pervasive systems allow users to access their information on the internet irrespective of their location. In addition, the advancement in devices miniaturization increases the number of portable devices connect to the internet like mobile phone, laptops, palmtops net books, PDAs, etc. In these scenarios we can consider different types of mobility. User mobility, Terminal mobility, Mobile access to resources.  ¿Ã‚ ½User mobility requires providing users with a uniform view of their preferred working environments ¿Ã‚ ½ user preferences and subscribed services ¿Ã‚ ½independent of their current positions in the network ¿Ã‚ ½.[1]  ¿Ã‚ ½Terminal mobility allows devices to transparently move and connect to different points of attachment ¿Ã‚ ½.[1]  ¿Ã‚ ½Mobile access is an emerging issue that involves th e dynamic adaptation of mobile-aware resources and services that mobile users and terminals can automatically retrieve regardless of their current location ¿Ã‚ ½.[1] Having considered the above types of mobility, mobile computing needs an advanced infrastructure which should dynamically trace and relocate mobile users and grant coordination between mobile entities. The infrastructure should also provide proper security level based on cryptographic mechanisms and tools. According to the given research paper three mobile computing services have been proposed: user virtual environment (UVE),mobile virtual terminal (MVT), and virtual resource management (VRM).  ¿Ã‚ ½UVE provides users with a uniform view of their working environments independent of current locations and specific terminals. MVT extends traditional terminal mobility by preserving the terminal execution state for restoration at new locations, including active processes and subscribed services. VRM permits mobile users and terminals to maintain access to resources and services by automatically requalifying the bindings and moving specific resources or services to permit load balancing and replication ¿Ã‚ ½.[1] SOMA-BASED MIDDLEWARE SOMA stands for Secure and Open Mobile Agent. SOMA is a service infrastructure for developing and implementing MA-based internet applications. SOMA consist of 4 layers. As shown in figure 1: Figure 1: http://www-lia.deis.unibo.it/Software/MA/Images/Mobile1.jpg The upper most layer is for mobility support which provides UVE (User Virtual Environment), MVT(Mobile Virtual Terminal), VRM(Virtual Resource Management). The next layer provides naming, security, migration, interoperability, persistence, communication and Quality of Service. The other two layers are a JVM (JAVA Virtual Machine) and a heterogeneous distributed system. SOMA is basically a JAVA based mobile agent which has been designed to provide the requirements of mobility, scalability, dynamicity, security and openness which are the typical issues in the internet scenarios. The two main goals to develop SOMA were interoperability and security. On one side, SOMA is based on detailed security model and provide a good range of mechanisms and tools to develop and enforce true security policies with flexibility. On the other side, SOMA is able to communicate and interact with different components of applications which are designed with different programming languages and platforms. Apart from interoperability and security features, SOMA is automatically and dynamically manageable and configurable and it provides the location abstraction to achieve scalability in a global scenario. The mobility of the mobile devices has introduced new security challenges like mobile can be hacked by the execution of malicious environment, may be cloned illegally to cause DoS (denial of service), or may be denial for roaming. These issues have been overcome in SOMA implementation as SOMA permits to protect both: agents come from malicious hosts and hosts from malicious agents. During the design and implementation of SOMA, number of challenges were faced to provide interoperability like SOMA application as server of COBRA, SOMA as COBRA clients, interoperability between COBRA components and SOMA, etc On the other hand, SOMA is a bit slow because of its extra security mechanisms, it involves different tools and techniques to provide more security which makes it slow as compare to other mobile agents but off course it is more secure than other mobile agents. As the name suggest secure and open mobile agent, its openness has introduced some more challenges to it especially for e-com merce applications so there is a need to improve it as nothing is perfect. Q2: All the MA(Mobile Agent) standards seem to be a promising platforms for implementing and developing applications in distributed, heterogeneous and open environments like the Internet. MAs try to overcome most of the limits of the conventional Client/Server model because of the basic features they have, such as autonomy and flexibility and can effortlessly integrate with the internet to extend accessibility of applications. Most of the application areas, like e-commerce, network management, mobile computing and information retrieval can benefit from the use of the mobile agent technology. There has been a lot of work done in this field. Like many mobile applications have been developed like we studies SOMA, there are some other application as well like SeMoA, Aglets, fraglets, etc. There are some advantages which all the mobile agents try to provide: Dynamic adaptation, flexibility, tolerance to network errors/faults, parallel processing, etc. Dynamic adaptation is the adaptation of t he different host environments. Tolerance to network faults means ability of mobile agent to operate without an active connection between server and client. Flexibility means to only source must be updated whilst changing an action of the agent. Comparing SOMA with other mobile agents, SOMA provides more security and openness as its name says. If we talk about SeMoA (Secure Mobile Agent) it has its own limitations, such as SeMoA is not very strong against a large number of Denial of Service (DoS) attacks like memory exhaustion. On the other hand SOMA has been designed taking into account security as a main property because SOMA protects both: agents come from malicious hosts and hosts from malicious agents. Another problem with SeMoA is that there are many classes in the core package that synchronize on the object of class itself. As local classes are shared and the visibility of local classes is global so any agent that access them and acquires a lock on such class objects blocks other threads to access them. On the other hand if we compare SOMA with fraglets which is very small computer program which has been designed to serve as a part of active network instead of a mobile agent. Fraglets have the ability to execute the codes on the path the travel by such as routers or hubs. Part 2: Q1:. Pervasive computing is a dream of personal computing where future living environments are saturated with non-intrusive, flawlessly operating services available for the user. To fully understand this dream these services are to adapt to the present situation of the environments, together with the economical/social situation of the user. Systems that use data about the state of either its system, users or the environment to settle in their behavior are called context-aware systems. Realizing context-awareness has introduced problems on different level: First, defining a context. Second, how and what can be adjusted when the context changes and where the context adaptation and definition comes from? Third, identify different contexts from sensor. Fourth, how a context can be represented and processed. But before that we have to understand the definition of context. The most cited definition of context by Dey is:  ¿Ã‚ ½Context is any information that can be used to characterize the sit uation of an entity. An entity is a person, place, or object that is considered relevant to the interaction between a user and an application, including the user and applications themselves ¿Ã‚ ½.[1] Representation: Unique Identifiers: The system should be able to recognize different type of contexts and environments in the real world. Uniqueness allow the reuse of that information without conflicting between identifiers. For example, If the user is driving a car so accelerometer can be used to detect the speed of the user. Validation: Validation should always be allowed for an information taken by the sensor before performing any action with it. For example, if the accelerometer indicates that the speed of user is fast (i.e. he/she is in the car) this does not mean that he/she is driving, this information should be validated before performing any action. For instance consider the condition that if I am driving I cannot answer the calls so reject the call and send a message saying I will call you later. But if I am in the car but I am not driving than I can answer the calls so the information from the accelerometer has to be validated before rejecting the calls. Uncertainty and incomplete information: As almost all of the context information of the real world is taken from the sensors, the information can be incomplete and uncertain. If we include reasoning uncertainty of the conclusions should follow the reasoning. Simplicity, reuse, and expandability: A system should supply only as expressive representation as necessary to maintain the domain knowledge. A simple representation endorse reuse and expandability. Simplicity, flexibility and expandability are among the requirements of context representation. Generality: Generality of context representation means the ability to support all types of context information. In my estimation, generality of a context representation is mostly described by its conceptual structure. Nevertheless, the clarity of a representation language which is used to generate the context information also vary its ability to generate context information at different levels of complexity. Q2. Introduction WAP (wireless application protocol) is a protocol to offer mobile data services. WAP is an open international standard that permits users to access global information instantly through any wireless device mobile phone, PDA, etc. WAP is normally supported by all operating systems. Browsers that uses WAP are called micro-browser. The rate of transfer of data is still very lower than the normal modem. On the other hand, I-mode is a complete mobile internet service that includes a large range of internet standards such as e-mail, sports results, weather forecast, news headlines, etc. This information is provided to the user by particular services from mobile carriers who charge them for these services. As the rate of transfer of the data is lower than the average modem, i-mode is not good enough for high resolution images and videos, it is basically sufficient for simple graphics and emails. Protocols WAP uses Wireless Markup Language (WML) for communication. while on the other hand i-Mode uses a different type of HTML which is called compact HTML (c-HTML). Capabilities of Devices WAP devices have to have a specific WAP browser while i-Mode supporting devices have to be able to display data from c-HTML. WAP capable devices show only textual information while i-Mode supporting devices shows multimedia images. WAP gives navigation among layered menus while i-Mode gives navigation via hyperlinks. Architecture WAP makes use of a unique language called WML (Wireless Markup Language) for interaction between a specific protocol translation device called a Gateway of WAP (GW) and information on the Internet. The GW communicates between HTML and WML, permits supply of WAP content to a WAP supporting device. iMode obeys a dissimilar approach to allow users to access IP-based services via their portable device. i-MODE is uses packet data transmission technology, a machine using this technology is continuously online. The transfer of the data makes use of the CDMA (Code Division Multiple Access). Graphics: One of the most main difference that appears, are clearly the dissimilar graphic capabilities. While it is right that i-MODE only allows simple graphics, that is much more than WAP. Charges: Another main dissimilarity is the capability of being always-on in i-MODE. As consumer are not charged for how long they serve online, it doesnt seem more suitable, but also less expensive than have to pay for the time they spent online. As it is not needed that dial-up before using the a variety of services based on IP, E-mail has become an SMS (Short Message Service). Part 3: Q1:. In CCA the InfoStations system is an infrastructural system concept offering many time, many-where access to wireless data services sustaining the portable communication process. This concept enables a variety of classes of portable devices to communicate with each other and with a large number of servers. Intelligent agents operating in the portable device users domain (Personal Assistants-PAs) and the InfoStations help to facilitate a contextualized and personalized environment for the system users. System functionality is offered as a set of flexible mobile services. To assist the personalization of these services, the User Agent Profile (UAProf) and Composite Capabilities/Preference Profile (CC/PP) terms are derived to enable the Personal Assistants express capability and preference information (CPI) about both the access device and the user as well. This makes sure that the offered services are adapted to suit the device capabilities, wireless network constraints and the user as well. Behavior of infoStation: Because of the fact that nature of the connection is defused, it is important for intelligent agents to work throughout the architecture. Being a PA (Personal Assistant), the agent may function automatically in order to convince any user service needs they encounter, while in or out of interaction with other agents which are working on InfoStation Centre or the InfoStation. The service sessions may be divided between different InfoStations, the personal assistant can make a service call while within the scope of an InfoStation, and then go out of the coverage area. During this time when the user goes out from InfoStation coverage, the personal assistant functions automatically adopt the functionality of the service till the user has completed the task. The InfoStations houses the Discovery, Presentation and Rendering Self-Service module, which is used to establish connections to mobile devices which enter within range. Also housed is a cache of recently accessed user and service prof iles, as well as a repository of available services.[4] Q2: Behavior of infoStation Centre: The InfoStation Centre stands at the centre of the system, which deals with the formation and updating of contents/objects throughout the system. From InfoStation Centre which acts as a central point, service updates can be spread across the whole system. All the infoStations are connected with the InfoStation centre which acts as a server of these infoStations. InfoStation centre is aware of all the devices connected to the infoStations but it communicates with infoStations only, it does not communicate directly to the devices connected to the infoStations. For instance a mobile device wants to communicate with the other mobile device connected with different InfoStation then the device will send a request to its InfoStation then the InfoStation send this request to InfoStation Centre and then InfoStation centre sends the request to the InfoStation to which the receiver device is connected with.

Dr Jack Perry Motivation case Essay

This case revolves around Dr. Jack Perry, the protagonist, is proprietary dentist clinic. Dr. Perry is a successful dentist in a small town of Cromwell in Canada. He had purchased the practice from a retiring dentist and has been successful in his practice considerably. However, he now faces a management problem of motivating his employees who are suffering from low morale and do not seem to be working as hard as they could to help increase the revenue of the clinic. Dr. Perry, had attended a dental conference in Chicago in 2005, and recalled two approaches to profit sharing which would help in motivating the employees. He now faces the dilemma as to which one of the two pay structures would be best suited for his practice as selecting a wrong pay structure could lead to further de-motivation of his employees. BACKGROUND OF THE CASE Dr. Jack Perry has managed to run a thriving dentistry practice in Cromwell which had a population of only 3000 and served an additional 7000 people from the surrounding areas. He had little competition in the form of 3 other dentists. Dr. Perry has sound financials and is witnessing a growth rate of 15 % annually. In conformance with industry norms Dr. Perry employs three categories of employees namely, receptionists, hygienists and assistants. At present he employs two part time receptionists, two full time hygienists, one full time assistant and one part time assistant. His employees were paid their wages at competitive hourly rates prevalent in the market. In addition to their hourly wages, they were given an Annual cash bonus of $400 during Christmas which was well appreciated by his employees. Dr. Jack Perry was quite involved with his staff by regularly discussing their work and salary on an informal basis. He allowed his employees 3 weeks holidays in a year. As a result Dr. Perry had virtually no staff turnover. Despite the his easy going manner, competitive salary and a pleasant work environment, Sandi the receptionist, had concluded that the morale was low among the staff, an observation Dr. Perry had made himself. OBJECTIVES To study the benefits and drawbacks of the two pay structures , its financial impact on the employees and how they would help him resolve the issue of low morale in the organization. To suggest the best suited pay-structure for Dr. Perry’s practice which would help him increase his collections by motivating his employees. CHARACTER SKETCH OF DR.PERRY Dr. Jack Perry is a dentist who has completed his graduation from an Ontario University dental school in 2011. He was a sole practitioner dentist in Cromwell, Ontario. Becoming a dentist in Canada was a rigorous process which required a lot of hard work and which included three years of study at the undergraduate level, followed by four years at an accredited dental school. Perry was happy with his work as he was giving competition to other three dentists in Cromwell. He was doing far better than his competitors and was proud of the financial success which came along with it. His business was now growing at 15 per cent annually. Perry had created a comfortable and easy going environment at the workplace. He used to have informal meetings with the staff annually to discuss the work and salary. His staffs were given three weeks of holiday per year. Not only this, but he also allowed his staff to take further unpaid vacation time as long as they can provide him with another staff member to handle their shifts. This gave the flexibility to the staff members as this thing made easier for them to spend some time with their families. All the team plans and organize the Christmas party before Christmas holidays. He used to give cash bonus for their hard work throughout the year. He was a benevolent boss. CASE ANALYSIS 1. The main reason for the decaying employee morale was the quick growth of the business. Dr. Perry’s employees were well compensated at competitive market rates and enjoyed a pleasant working environment. The annual growth of the business (15%) meant that his employees were making relatively less money than Dr. Perry himself. The current pay structure did not have any provision for any category of employees to earn a proportion of the profits. Every employee has a fixed hourly salary. Thus, a bigger business meant that they felt like slave labourers since they were aware of the increase in the practice’s revenues and number of patients. 2. Dr. Perry’s revenues largely depended on the hygienists who generated about 40% of the revenues. Even the receptionists played a vital role in adding to the revenue by filling in cancelled appointments. His assistants too contributed by playing the role of nurses by comforting the patients which further helped in patient retention. Thus it would seem only fair that a part of the profits must be shared with the employees in the form of a variable pay structure. 3. As per the conference which Dr. Perry had attended, the first approach of remunerating the employees focused on the contribution of the hygienists only. As per this approach, the hygienists would be paid purely on a commission basis of around 40% of the total earnings. The main advantages of this system are: It recognises the direct effect of the hygienists’ efforts on the revenues of the practice and rewards them for the same. A 40% commission would be financially more beneficial to the hygienists assuming the current level of collections. Also it is forecasted that such a pay structure would result in an increase in the billings by about 13%. The major drawback of this system is that it simply does not completely recognize the contribution of the receptionists and the assistants in the revenue generation of the firm. The pay structure does not clearly define how commission would be linked to the total earning of the receptionists and the assistants. Also, by making the earnings of the hygienists completely dependent on the revenue, it may lead to dissatisfaction of the hygienists of the collections did not increase. 4. The second approach states that the employees should be given a share of the profits at a pre established percentage over and above their hourly wage rates. This method ensured that : Some parts of the profits were distributed to all the categories of employees. At the same time since the employees would receive their hourly rates in any case, it would give them a sense of security and eventually help in maintaining the pleasant work atmosphere. However, this method did not distinguish between the categories of employees who contributed more to the revenues than those who contributed comparatively less. This could lead to de-motivation of the hygienists who had a direct impact on the revenues of the companies. Solutions/Suggestions For Hygienist : 1. Perry’s Clinic should recognise best skilled hygienists. Perry should conduct special trainings for the underperformers and bring them to the same level. 2. Targets of hygienists need to be on a similar alignment as that of the firm. 3. Teamwork needs to be motivated through annual bonus. 4. Incentives can be introduced to keep the results persistent. 5. The firm should control the cost through effective pay strategy. The above decisions could have the following effect on the hygienists – their income would increase; the effort put in by an individual would benefit him/her i.e. every individual is responsible for his/her incentives. Thirdly they would get an opportunity to work with an efficient peer group thereby nurturing each other. For Assistants & Receptionists: 1. The firm should encourage wage earners to spend time on highly skilled tasks. 2. Decrease interoffice concern about peer pay. Pay should be based on training level. 3. The weekly payroll should be known. 4. Annual bonus would motivate team work and coordination. By implementing these they would have stable pay, little daily pressure to up sell services. Their pay easily calculated each week. It would allow them to take time off providing high quality of work. CONCLUSIONS In the scenario where Dr. Perry business is growing at a healthy rate it is important to continuously monitor pay structure of the firm and revise it from time to time since remuneration is directly related to the motivation level of the employees. Dr. Perry must change the pay structure to accommodate profit sharing with the employees in the form of a bonus which would be a percentage of the total profits of the practice, in the case of increased revenues for that particular year. This method is better for the business at this stage because the practice is still in a growth stage. The profits can be divided among the different categories of employees in a number of ways. A drastic change in the pay structure from fixed to completely variable is not recommended because in case of lower collections in any particular year, it may lead to lower earnings for the employees. This pay structure can be further revised in the future to increase the profit sharing element in the remuneration of the employees as the firm grows bigger. MANAGERIAL LEARNINGS 1. Monetary benefits motivate people to perform better in most cases. It is important for managers to understand the link between the pay structure and the motivation levels of employees. Merely high wage rates may not be sufficient to motivate the employees and they must given a fair share of the profits earned by the firm. 2. Performance linked Variable Pay (PLVP) is a salary component present in most of the MNCs. This keeps the employees motivated to continuously increase their productivity rather than a fixed salary which may lead to a laid back style of working thereby impacting the performance negatively. 3. It is important for mangers to know the contribution of individual employees and different categories of employees and must frame the pay structure in accordance with the same. This would ensure that employees are rewarded sufficiently for better performances. 4. Keeping the market standards in mind, pay – structures must be constantly monitored and should be revised along with the growth of the firm in terms of revenue earned and the volume of business for employees of all levels. 5. Firms disclose their revenue generated through Quarterly/Semi Annual Meets. Managers must make sure that the employees understand not only the revenue aspect of a growing firm but also the increased costs associated with them and therefore emphasise on the need for higher productivity from the employees.

Essay on Psychology of Successful Students - 1132 Words

What means to be a successful student? Being productive at studies, working at part-time job, or expressing talents? Yes, in the modern world all these activities can characterize a student as a successful one. The reason for this statement is that the time when the only student’s mission was to study had passed. Our life gets faster and faster rhythm, so it is very important to be everywhere and to do everything. I, as a student, see this picture very clear in daily life: parents expect the highest grades in the University, employers ask for more work experience, and, finally, the talents should be expressed. Definitely, there is no necessity to do all this things in certain period of life, but there is a possibility to do it.

This aspect is very important part of my research which shows the direction to everybody – everything should be done today, not tomorrow, because nobody knows whether tomorrow will come at all. The term, connected to the previous one, is positive thinking. This term sounds simply, nevertheless this term is quite difficult. One thing is to know what positive thinking is, and totally different thing is to apply such way of thinking in your life. Positive thinking is something which helps us to color our life. It helps to overcome stress and look positively at the future. In my research positive thinking will help students to believe in their ability and power. Time management skills refer to how effectively it is possible to use student’s time. Careful planning can be a good base for all the activities in student’s life. One more term – preferable learning style – means the certain way of learning which suits to certain stud ents. According to psychologist, there are seven styles of learning.

Abraham Lincoln s The Battle Of Gettysburg - 984 Words

While in office, Abraham Lincoln faced an almost unsurmountable task. Not only did Lincoln try to eradicate the idea of a human owning another human, but he also had to keep unity among the country. With a civil war raging, and a divided country in anarchy, Lincoln did not have the odds in his favor. After the Battle of Gettysburg, Lincoln took a step back to show everybody, through the Gettysburg Address, the doom that America will face if it were to continue down the path that it is heading. Lincoln didn’t just accomplish this goal, but he also created an underlined metaphor, between the fallen heroes of Gettysburg, and the fate of America. The most predominant message in Abraham Lincoln’s speech was that if America didn’t rise above this outlandish war being fought, then the entire country would soon face the same fate as the fallen participants in the Battle of Gettysburg. Abraham Lincoln performs the remarkable task of using the entire timeline of America. In only ten sentences, he is able to discuss previous, current, and future American events. Starting in the past, Lincoln reminds Americans of the excitement felt during the creation of a new and prosperous nation. â€Å"Four score and seven years ago our fathers brought forth, upon this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal†.
