WSN is a wireless network made of wireless sensors that is used to monitor the system, environmental or physical conditions. Network coverage is a critical Quality of Service parameter in the design of WSN. The sensing model used to design the network decides the coverage. In this paper, the effects on sensing coverage by multi-path fading and shadowing effects have been studied. A model for calculating coverage probability has been derived for an environment in presence of shadowing effect combined with multi-path fading. Deployment scheme directly influences the performance of the WSN. A multiple deployment scheme is proposed for shadowed and non-shadowed environments using Rayleigh and shadow fading. For the same value of sensing coverage, a significant depreciation in the required number of nodes is shown.
