摘要: 移动自组网(MANET)是自治的无基础设施的网络,它通过IP路由支持多跳无线通信,它被用于没有基础设施存在的动态变化的场景。多数自组网路由协议利用节点之间固有特性即相邻节点的信赖关系进行协作转发数据包。这种信赖模型使得恶意节点利用插入错误的路由更新、重放过时的路由信息、改变路由更新、或广播不正确的路由信息来瘫痪自组网。针对自组网的缺陷提出了一种认证路由策略来解决这些问题,同时也列举了仿真实验结果。

Abstract: Mobile Ad hoc networks(MANET) are autonomous,infrastructureless networks that support multi-hop communication through IP routing.MANET is used to support dynamic scenarios where no wired infrastructure exists.Most ad-hoc routing protocols are cooperative by nature,and rely on implicit trust-your-neighbor relationships to route packets among participating nodes.This na?觙ve trust model allows malicious nodes to paralyze an ad-hoc network by inserting erroneous routing updates,replaying old routing information,changing routing updates,or advertising incorrect routing information.We propose an authenticated routing to overcome these disadvantages and also show the results of several simulation experiments in ad hoc networks environment.

Key words: MANET, routing protocol, secure routing protocol
