Energy Efficient Seamless Service Provisioning in Mobile Cloud Computing

Abstract

Accessing Cloud via mobile device proves to be costly because of issues with wireless network. Due to communication overhead, offloading of application execution to Cloud consumes more energy than executing in the device itself. This paper proposes a novel framework in which application execution is offloaded to both Cloud and mobile ad hoc Cloud, in order to reduce this communication overhead. Distributed/Parallel execution of tasks is done to reduce the waiting time of mobile device, provided the cost of offloading is less, compared to cost of executing the application in device. Seamless service provisioning is achieved in this framework, by measuring the signal strength of the wireless medium. Once the signal strength threshold is reached, interim results are got from the device to which task is offloaded. This paper proposes the framework for energy efficient seamless service with features like, connecting heterogeneous mobile devices to form mobile ad hoc Cloud, service discovery in mobile ad hoc Cloud and offloading decisions.
