GAAM: an energy conservation method using code migration for ad hoc sensor networks

Ad hoc sensor networks are used in different hostile environments, like forests, battle fields, etc. The nature of these surroundings makes power recharging of the network devices very difficult or even impossible. Therefore, energy conservation is one of the main concerns of such systems. As most of these systems consist of different procedures resided in sensors that communicating by means of RPC, placing related codes near each other can extremely reduce total energy utilization. In this paper, we have proposed GlobAl/locAl Migration (GAAM) to decrease power utilization with the help of code migration. Then, the mathematical analysis of the proposed method is presented, where the correctness of the scheme is proved with an extra premise. Moreover extended issues provide some ideas to improve the outcomes even more. Simulation results indicate that the total consumed energy is reduced by 50 percent, using GAAM.
