Abstract

When a sensor network is deployed for monitoring a protected region, topology control is usually used to save energy consumption, especially in a dense deployment. In this paper, we propose a new and simple topology control protocol, Convergent SparseDT, which controls the network density pretty well, and disposes of some important faults of classical topology control protocols while working with dense sensor network. It is a compromise between the energy consumption, network congestion and the area coverage. It guarantees the coverage of most of the monitored area with almost negligible communication and computing overhead. The performance of this protocol is thoroughly analyzed and simulated in NS2 simulator.
