Abstract: In order to detect the captured nodes as early as possible, just before they rejoin the networks, a node capture early detection method was proposed for wireless sensor networks (WSN) in asynchronous sleep mode. The proposed scheme was based on communication monitoring between neighbor nodes and a Hello message scheduling mechanism was employed to ensure the reception of Hello messages between asynchronous sleep nodes. Moreover, the local collaborative decision of common neighbors was explored to improve the detection accuracy rate. Simulations show that the proposed scheme outperforms other typical methods in terms of effectiveness including detection rate, false positive rate and false negative rate.
