选择性丢弃攻击检测方案

Detecting Selective Discarding Attacks Scheme

在无线传感器网络中,针对被俘获的恶意节点发动的丢弃合法数据包的攻击行为,提出了选择性丢弃攻击检测方案.该方案使用邻居检测点监听转发节点是否转发了数据包,防止数据包被恶意的丢弃.检测点在发现转发节点恶意丢包行为时,会执行转发数据包的任务,同时生成警报信息给BS节点.BS节点收到一定数量的警报信息,采取相应的措施隔离恶意节点.仿真结果表明,该方案能够很好的抵御恶意节点的丢包行为.

In this paper,detecting selective discarding attacks scheme for malicious node dropping legal packets from compromised nodes is proposed in wireless sensor.The scheme uses neighbors detection node to monitor whether forwarding node forward the packets,and prevent malicious node from dropping packets.Detection node executives function to continue forward packets and generate alarm information to a BS node when find malicious node dropping packets.As collecting a certain number of alarm information,BS node will take corresponding measures.The simulation results show that this scheme can against malicious node of the lost package behavior.
