Coverage Statistics of Distributed Sensor Fields With Heterogeneous Range Sensitivity

摘要

This report presents analytical results for the coverage provided by a system of randomly distributed sensors having heterogeneous range sensitivities. The need to rapidly deploy even a moderately large number of sensors on short notice could place limitations on sensor quality. In particular, the requirement that all sensors have the same range sensitivity could pose a serious problem to the timely deployment of the sensor network. Through an entirely probabilistic approach, coverage statistics for a system of randomly distributed sensors having heterogeneous range sensitivities are obtained. Simulation studies that support the theoretical results are provided. Throughout this report, there are remarks on the implications of the analytical results on design guidance and sensor deployment.
