Abstract
In a traditional mobile ad-hoc network (MANET), if two nodes are engaged in a session and one of them departs suddenly, their communication is aborted. The session is not active any more, work is lost and, consequently, the energy of the batteries has been wasted. This paper proposes a model that uses a cloud service to register, save, pause and resume sessions between MANET member nodes so that both work in progress and energy are saved. A checkpoint technique is introduced to capture the progress of a session and allow it to be resumed. This is an additional service to our cloud management of the MANET. The model proposed in this paper was tested on Android-based devices and an Amazon cloud instance. Experimental results show that the model is feasible, robust, saves time and, more importantly, energy if session breaks occur frequently.
