Performance Analysis for Intrusion Target Detection in Wireless Sensor Networks

Target detection and field surveillance are among the most prominent applications of wireless sensor networks.   However, the sensing capabilities of sensors are affected by environmental factors in real deployment.  This paper investigates the problem of detecting probability in a log-normal shadow fading environment.  It presents an analytic method to evaluate the detection probability by at least k sensors under practical considerations.  Furthermore, we also shows that shadow fading makes significant influence in detection probability compared to unit disk sensing model through extensive simulation experiments.
