In this paper, a physical layer security analysis of wireless sensor network in the presence of an attacker, employing opportunistic scheduling approach, is presented. The intended as well as unintended transmission paths experience the Weibull fading. A novel analytical expression for the intercept probability is derived. In order to emphasize the advantages of the opportunistic scheduling approach, a comparative analysis with round-robin and optimal scheduling schemes is also given. The impact of a number of active sensors and the impact of fading channel conditions over main and wiretap channels on the intercept probabilities is obtained. The accuracy of theoretical results is confirmed by independent Monte Carlo simulation results.
