Abstract: A routing security mechanism for on-demand routing in MANET— NRR (neighbor monitoring, node reputation and route healing) is examined and proposed. This mechanism includes three parts: neighbor monitoring and detecting, node reputation and route healing. This mechanism realizes fully distributed instruction detection. The theme can prevent inner non-cooperative nodes from attacking, can heal the damaged routing caused by attacks and ensure the stability of the on-demand routing protocol in its best.

Key words: MANET, routing security, neighbor monitoring and detecting, non-cooperative nodes

摘要：

提出了一种适用于MANET按需路由协议的路由安全机制NRR。该方法通过邻居节点监测机制、节点名誉机制和路由修复机制3个组成部分，实现了完全分布式的入侵检测，能防御典型的内部节点攻击，并能修复因攻击而造成的受损路由，最大程度地保证了路由协议的稳定性。
