Abstract

Density control is an important technique for prolonging a lifetime of wireless sensor network. To reduce the energy consumption, it is desirable to minimize the overlapping sensing area of the sensor nodes. In this paper, we study the problem of energy-efficient area coverage by the regular placement of sensors with two given sensing ranges. We propose new polygon-based deployment patterns and suggest analytical method to estimate their efficiency. Calculations show that the new models outperform existing ones.
