Evaluation of Cooperative Task Computing for Energy Aware Wireless Networks

In this paper we propose cooperation on task-set computation for cooperative groups of mobile wireless terminals. Energy consumption for future generation terminals is important, calling for new innovative concepts to alleviate the present evolution of evermore energy hungry terminals. Related to cooperative concepts a novel energy conservation method is proposed, which we will refer to as DVS. Our proposed method uses abstractions of traditional multi-processor environments, where terminals are considered as processing units connected by short range wireless networks. Energy conservation is obtained by the well known method of dynamic voltage scaling, which has proven to generate near optimum energy schedules of tasksets. Our simulation experiments show that up to 40% energy reduction on two cooperating terminals is obtainable. This is compared to a single energy aware terminal.
