Abstract

Coverage and energy efficiency are two important concerns in wireless sensor networks. In this paper, a coverage and energy efficient (CEE) task assigning strategy is presented. The basic idea of CEE is to assign tasks according to node's coverage degree and remaining energy. Based on this idea, grid-based coverage and energy efficient (GCEE) information gathering protocol is designed. GCEE is simulated with NS-2. How the various parameters affect the fraction of the survived nodes and the area energy balancing of the network is shown in simulation results.
