摘要

Network Coverage in a wireless sensor network (WSN) depicts the extent of area covered by sensors. Coverage is also considered a factor responsible for Quality of service. Coverage can get affected due to multiple reasons such as low energy, limited number of nodes and node failure. Node failure happens due to various reasons such as noise and low battery power. In this paper we analyze the effect of failure of nodes on network coverage in wireless sensor networks in the presence of shadowing with edge effects and Rician fading. We find the node failure has a greater impact on fading environment than the shadowing environment with the number of nodes increasing at a rapid rate to give good coverage.
