Abstract
Energy efficient self-organization is a crucial method to prolong the lifetime of wireless sensor networks consisting of energy constrained sensor nodes. In this paper, we focus on a distributed node scheduling scheme to extend network lifespan. We discuss the network coverage performance when sensor nodes are deployed according to Poisson point process and reveal the internal relationship among the required coverage performance, expected network lifetime and the intensity of Poisson point process. Also the impact of uniformly distributed time asynchrony on network coverage performance is analyzed. Simulation results demonstrate that the proposed scheme works well in the presence of time asynchrony.
