An Energy Efficient Cross-Layer Clustering Scheme for Wireless Sensor Network

In the area of wireless sensor networks, achieving minimum energy consumption is a very important research issue. At present, a number of energy efficient protocols have been proposed, mostly based on a layered design approach, which means that they are focused on designing optimal strategies for single layer only. In this paper, we present a cross-layer cluster scheme by optimizing the routing and the scheduling. In order to average the energy consumed by the nodes closer to the base station, we take a cluster scheme that the cluster head nodes could be chosen based on the residual energy. Through the two aspects, we are able to achieve the purpose of prolonging the lifetime of wireless sensor network. Through simulation using NS-2, we prove the performance of the presented strategy is better than a layered design approach.
