Since the nodes of WSNs are always deployed on the outside, nodes are easy to be captured. The traditional detection approaches of capture attack can be categorized as approaches based on time of absence and approaches based on target tracking. The former only suitable in static WSNs and the latter usually requires a large communication cost. In this paper, a novel node capture attack detection approach is proposed in dynamic WSNs. Through this approach, every node record its neighbors and detect new nodes in real-time, if new nodes join in the network, a new node tracking algorithm is performed in WSNs and find out which of them are captured by adversaries. Simulation results show that, this method can greatly improve the detection accuracy in dynamic WSNs, and the communication cost is low. |
