We consider in this paper a single-channel wireless sensor network (WSN) where communication among sensor nodes are subject to jamming by an attacker. In particular, we address the detection of a jamming event, and investigate the optimal network defense strategy to mitigate jamming effects. A multiple-monitor distributed detection structure is considered. The optimal detection scheme is developed under the Bayesian criterion, with the goal of minimizing the error probability of detection at a fusion center. For the optimal network defense strategy, we formulate and solve the design problem using a constrained maximization problem by jointly considering Quality-of-Service and resource constraints of WSNs such as communication throughput, energy, and delay.
