一个高效的双向无线Ad Hoc网络匿名路由协议

Efficient bidirectional anonymous routing protocol for wireless Ad Hoc networks

分析了Ad Hoc网络现有匿名路由协议的不足,提出了一个轻量级的,能提供良好匿名保护的基于反应式的源路由协议的匿名路由协议。该协议利用布隆过滤器实现了在ASR中定义的身份匿名、路由匿名和位置/拓朴匿名。它主要使用的是哈希运算,并在不破坏协议匿名性的前提下,通过控制路由请求包避免其在网络中传输时间过长而提高整个网络的效率。协议中建立起的匿名链路具有双向性,这也降低了匿名协议的耗费。仿真数据与分析证明了新协议的有效性与匿名性。

A lightweight anonymous routing protocol was presented, which was based on reactive source routing. It enables complete anonymity of identity, route and topology defined in ASR, using Bloom Filter. The main computationally intensive operation in use is hashing and it does not need to use any public key operation. Without eroding the topology anonymity, it actualizes hop control to avoid the excessive propagation of route requests in order to enhance the efficiency of the network. In addition, the anonymous links established in this protocol are bidirectional, which also helps to reduce the overhead of the anonymous protocols. Detailed analysis and simulation show that the new protocol achieves good anonymity and efficiency.
