Power - Aware Resource Management for Sensor - Actor Networks

Abstract

Mobile sensor actuator networks have been applied in a wide range of real-world applications. Because nodes in sensor networks are powered by batteries, two major problems arise. First, the nodes do not last long because of limited power supply. Second, only limited amount of data can be transferred if proper mobility strategies are not designed. In this research, we propose the concept of pipelining of mobile nodes to asynchronously transfer and relay data in the network. Through a number of simulations we examine the design tradeoff of performance and energy cost. Performance evaluation through simulations has been conducted by number of mobile nodes. The proposed pipelining strategy yields three major benefits. First, as the number of mobile nodes increases, rate of data transfer increases. Second, energy required per data transfer decreases. Finally, life time of the network increases compared to traditional non-pipelining mobility strategy.
