A Novel Framework for Coverage Optimization of Sensor Network

Abstract

In this paper, the coverage optimization of a circular sector sensor network in a region is considered. We propose a new framework to solve this problem, in which a so-called optimization matrix is constructed to addresses the coverage strength of every sensor to all sampling points, and the overlap coverage strength of every two sensors. Then, the coverage optimization of sensor network is equivalent to maximize the coverage strength of all sensors to all points in the target space subject to each overlap coverage strength of every two sensors is smaller than a threshold. This framework is general and can be applied to any networked sensors with different coverage models or geometries. Moreover, a simulation example is provided to illustrate the effectiveness of the proposed method.
