WSN异步休眠模式下节点捕获早期检测方法

针对异步休眠模式的无线传感器网络（WSN），提出了一种节点捕获早期检测方法，在被捕获节点重新加入网络之前即被检出，实现对网络攻击的及早发现.该方法基于相邻节点间存活性监控，并通过节点声明消息统一调度广播机制，保证异步休眠节点间声明消息的接收，同时，在决策过程中采用本地协同决策方式以提高正确率.仿真结果表明，该方法在检测率、误报率和漏报率等有效性方面均优于其他现有典型方法.

A Node Capture Early Detection Scheme for WSN in Asynchronous Sleep Mode

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.
