Using mobile agent in clustering method for energy consumption in wireless sensor network

In wireless sensor networks where the source nodes are close to one another and generate a lot of sensed data, traffic with redundancy, transmitting all sensed data by individual nodes not only wastes the scarce wireless bandwidth, but also consumes a lot of battery energy. In this paper we introduce an algorithm, which make better use of energy and bandwidth that are two restrictions in wireless sensor networks. In the algorithm, a mobile agent is used to cluster the network and also create the tour to obtain collected data from each cluster-head and deliver back to the sink node. With appropriate parameters set, simulation shows that proposed algorithm exhibits better performance than original direct diffusion in terms of energy consumption.
