The paper introduces Ad hoc network. The single path routing algorithm and the mult ipath algorithm are analyzed and compared. According to the on demand idea, inde pendent multipath algorithm based on DSR is proposed for Ad hoc networks.

• 目前Ad hoc网络正成为网络发展的热点，该文介绍Ad hoc网络，分析比较了单 路径和多路径算法，就多路径算法加以分析，同时借鉴按需路由的思想，在DSR协议的基础 上提出了Ad hoc网络的一种按需的独立多路径算法。
