The proliferation of mobile devices, coupled by the increase in their capabilities, have enabled the establishment of a rich mobile computing platform that can be utilized in conjunction with cloud services. In this chapter, we overview the latest mobile computing models and architectures focusing on their security properties. In particular, we study a wide range of threats against the availabi...

In this paper, we propose an adaptive mobile system that uses mobile grid computing to achieve infeasible work in mobile device. Recently, grid computing has gained significance for its ability to achieve certain goals by sharing the idle resources of computing devices, and thus overcoming the various constraints of the mobile computing environment. In the mobile environment, it is very importa...

Mobile computing paradigm has emerged due to advances in wireless or cellular networking technology. This rapidly expanding technology poses many challenging research problems in the area of mobile database systems. The mobile users can access information independent of their physical location through wireless connections. However, accessing and manipulating information without restricting user...

Message oriented middleware (MOM) is a specific class of middleware that operates on the principles of message passing or message queuing. Existing MOM syste doesn’t support the function for mobile computing environment. In the near future, requirements of mobile computing will increase and more dynamic service for mobile computing will be required. And i nteracting with wireless networks is be...

Information Technology (IT) is the study of systems especially computers for storing, retrieving, and sending information. It uses any networking and other physical devices, infrastructures to secure and exchange all forms of electronic data. IT is used globally as a major portion of daily life and we use it nearly every day within organizations for many reasons. Our computers, mobile phones an...

Mobile cloud computing is gaining popularity among mobile users. The ABI Research predicts that the number of mobile cloud computing subscribers is expected to grow from 42.8 million (1.1% of total mobile users) in 2008 to 998 million (19% of total mobile users) in 2014. Despite the hype achieved by mobile cloud computing, the growth of mobile cloud computing subscribers is still below expectat...

Together with an explosive growth of the mobile applications and emerging of cloud computing concept, mobile cloud computing (MCC) has been introduced to be a potential technology for mobile services. MCC integrates the cloud computing into the mobile environment and overcomes obstacles related to the performance (e.g., battery life, storage, and bandwidth), environment (e.g., heterogeneity, sc...

Mobile devices are becoming the primary platforms for many users who always roam around when accessing the cloud computing services. From this, the cloud computing is integrated into the mobile environment by introducing a new paradigm, mobile cloud computing. In the context of mobile computing, the battery life of mobile device is limited, and it is important to balance the mobility performanc...
