A coverage configuration scheme of wireless sensor networks base on collaborative sensing in shadow fading

This paper analyzes the coverage problem under the shadow fading of the WSN with sensors deployed in the monitor region randomly and high density. Because the target sensed probability by multi-sensors is better than the single sensor, in the paper the collaborative sensing model is deduced, and then a coverage configuration scheme based on cooperative sensing model under shadowing is promoted. In the coverage scheme the judgment of the area coverage is simplify to the judgment of some special points under Voronoi dividing. The simulation results show that our method is more excellent than other protocol in aspects of the number of active nodes and the network coverage quality.
