This chapter describes an object-based workflow paradigm to support long and short duration transactions in a mobile e-commerce (or m-commerce) environment. In the mobile computing environment, the traditional transaction model needs to be replaced by a more realistic model (called a “workflow model”) between several clients and servers that interact, compete, and cooperate, realising an intergalactic client-server program (ICSP). The various types of task patterns that arise in m-commerce (e-checking, shipping goods, purchasing, and market forecasting) require a subjunctive, or “what-if,” programming approach, consisting of intention and actions for trial-error design, before an actual commitment is made. Eiffel, iContract tool of Java, and UML are powerful languages to implement the intergalactic client-server program (ICSP). They provide for a software contract that captures mutual obligations through program constructs to take care of the unpredictable nature of connectivity of the mobile devices and the networks, as well as the trial and error program design required in m-commerce.

This overview describes an object-based workflow paradigm to support long and short duration transactions in a mobile e-commerce (or m-commerce) environment. In this environment, the traditional transaction model needs to be replaced by a more realistic model, called a “workflow model” between clients and servers (peers) that interact, compete and cooperate, realizing an intergalactic client-server program. The various types of task patterns that arise in m-commerce, for example, reservation, purchasing, require a “what if” programming approach consisting of intention and actions for trial-error design before an actual commitment is made. Such an approach enables us to take care of the unpredictable nature of connectivity of the mobile devices and the networks and also provide for the trial and error program design required in m-commerce.

Mobile Cloud Computing (MCC) which combines mobile computing and cloud computing, has become one of the industry ring words and a major conversation thread in the IT world with an explosive development of the mobile applications and emerging of cloud computing idea, the MCC has become a possible technology for the mobile service users. The concepts of Cloud computing are naturally meshed with mobile devices to allow on-the-go functionalities and benefits. The mobile cloud computing is emerging as one of the most important branches of cloud computing and it is expected to expand the mobile ecosystems. As more mobile devices enter the market and evolve, certainly security issues will grow as well. Also, enormous growth in the variety of devices connected to the Internet will further drive security needs. MCC provides a platform where mobile users make use of cloud services on mobile devices. The use of MCC minimizes the performance, compatibility, and lack of resources issues in mobile computing environment.

Due to the rapidly increasing of the mobile devices connected to the internet, a lot of researches are being conducted to maximize the benefit of such integration. The main objective of this paper is to enhance the performance of the scheduling mechanism of the mobile computing environment by distributing some of the responsibilities of the access point among the available attached mobile devices. To this aim we investigate a scheduling mechanism framework that comprises an algorithm provides the mobile device with the authority to evaluate itself as a resource. The proposed mechanism is based on the proposing of “self ranking algorithm (SRA)” which provides a lifetime opportunity to reach a proper solution. This mechanism depends on event-based programming approach to start its execution in a pervasive computing environment. Using such mechanism will simplify the scheduling process by grouping the mobile devices according to their self -ranking value and assign tasks to these groups. Moreover, it will maximize the benefit of the mobile devices incorporated with the already existing grid systems by using their computational power as a subordinate value to the overall power of the system. Furthermore, we evaluate the performance of the investigated algorithm extensively, to show how it overcomes the connection stability problem of the mobile devices. Experimental results emphasized that, the proposed SRA has a great impact in reducing the total error and link utilization compared with the traditional mechanism.

Security Issues

Now a day’s mobile communication has become a serious business tool for the users. Mobile devices are mainly used for the applications like banking, e-commerce, internet access, entertainment, etc. for communication. This has become common for the user to exchange and transfer the data. However people are still facing problems to use mobile devices because of its security issue. This paper deals with various security issues in mobile computing. It also covers all the basic points which are useful in mobile security issues such as categorisation of security issues, methods or tactics for success in security issues in mobile computing, security frameworks.
