摘要: 无线传感器网络通常部署在无人值守的敌对环境中,容易受到攻击节点的影响,给其应用带来较大挑战。针对该问题,利用移动信标节点,提出一种基于接收信号强度指示器(RSSI)一致性实现未知节点安全定位的方法。该方法通过计算未知节点接收到的数据包RSSI的方差,将方差较小的一组所对应的节点信息剔除,从而抑制虫洞攻击对定位的影响。仿真结果表明,该方法能有效消除虫洞攻击对节点定位的影响。

Abstract: Wireless Sensor Network(WSN) is often deployed in hostile environments,in which malicious attackers can easily disrupt the nodes’ localization procedure to challenge the WSN-based applications.A new method of secure unknown node localization is proposed on the basis of the consistency of Received Signal Strength Indicator(RSSI) by using mobile beacon node.The proposed secure localization scheme can counteract the impacts of wormhole attack by eliminating the group of beacon information with a smaller variance of RSSI.Simulation results show that this method can effectively eliminate the influence of wormhole attack on node location.

Key words: Received Signal Strength Indicator(RSSI), Wireless Sensor Network(WSN), wormhole attack, mobile beacon node, secure localization
