Abstract


The advancement in wireless technology and rapid growth in the use of mobile devices in mobile paradigm have the potential to revolutionize computing by the illusion of a virtually infinite computing infrastructure. This new mobile paradigm enabled mobile devices to support data and transaction management in addition to the static nodes. A mobile device from anywhere in the wireless environment could utilize seamlessly a large computing power or any other resources in order to provide effective data and transaction process. In addition, advancement in wireless network together with ubiquity of devices has resulted in storing and retrieving incredible volumes of knowledge provided by data in the mobile devices. Knowledge provided by data from mobile system has become very essential in many day-to-day applications. However, transaction management and knowledge discovery in mobile environment faces several challenges such as scarce bandwidth, limited battery resources, asymmetry in wired and wireless connectivity, asymmetry in mobile and fixed hosts, and mobility of host and their limitations. In addition to the traditional mobile system challenges, it also faces many challenges such as dependency on continuous network connections, data sharing applications and federation with multiple service providers.
Due to these challenges, data loss, frequent disconnection, unpredicted number of wireless and wired access and high transaction aborts has occurred in data and transaction management over distributed mobile paradigm. To realize data management in mobile cloud, Surrogate Object based Mobile Transaction is proposed to deal with the fundamental issues of asymmetry problems, latency problems, low abort rate and disconnection.
The proposed strategy caches the data in the surrogate object which helps in reducing the average transaction time. The required reliability is provided by sending the transaction request to surrogate object and network lifetime is maximized by migrating the surrogate objects in a way to avoid improper load balancing. The performance of proposed models have been evaluated and compared with existing models by simulation.
