For the blindness of randomly deploying Wireless Sensor Network(WSN),a strategy is proposed that WSN nodes are deployed following random uniform distribution rule.This paper demonstrates that in the perception area,a large number of sensors with randomly deployment obey Poisson distribution,by establishing the model of WSN node distribution model,find the relationship between the percentage of coverage area and the nodes density of target area.It proposes a scheme that how to estimate the required number of sensor nodes in target area.Experimental results show that the proposed strategy not only guarantees the coverage and connectivity of the WSNs,but also reduces costs effectively.
