Abstract

Density control is a key technique in dense sensor networks for prolonging network’s lifetime while providing sufficient sensing coverage. In this paper we present a new density control algorithm called ESSC(Enhanced Sponsored Sector Coverage) based on the SSC(Sponsored Sector Coverage) proposed by Tian Di. ESSC algorithm takes note of the deficiency of the SSC algorithm and modifies the model of SSC to minimize the active node number. Analysis and experimental results show that ESSC can use up to 15%~25% fewer active nodes than SSC while promising the performance of the network surveillance.
