Determining the required number of sensors to be deployed is a critical decision for surveillance wireless sensor networks. In this paper, we discuss the trade-off between the number of sensors and the breach detection probability considering the effects of sensor parameters. We present the weakest breach path problem formulation and provide a solution by utilizing the Dijkstra’s shortest path ...
