摘要
由于Ad Hoc网络的自组织、动态变化特性,极易受到入侵节点的攻击。针对Ad Hoc网络安全性方面的不足,提出一种改进的基于簇的入侵检测策略,通过在一跳范围内随机选举簇首节点,利用簇首节点对网络节点的收发状态进行监视,从而防止了入侵攻击在网络中的蔓延。利用OPNET软件对成簇和入侵检测策略进行了仿真,仿真结果表明,该策略降低了由网络攻击引起的负载开销,提升了网络吞吐性能.
Ad Hoc network is self-organized,dynamic and highly encounters resend and counterfeit assaults etc.This paper aims at the network security deficiency of Ad Hoc,which is based on dynamic source routing protocol.An improved strategy for clusters of intrusion detection was proposed,in which a cluster head node was elected within one hop randomly and the sending and receiving state of other nodes was detected.The strategy can effectively prevent the spread of invasion attacks in the network.The OPNET software was used to simulate the process of the cluster forming and the intrusion detection.The simulation result showed that the strategy reduced the load caused by the attack of the network and improved the throughput of the network.
