Ad Hoc网络是一个由多个无线移动的主机组成的临时网络，不需要任何集中管理，各个节点通过相互转发数据包进行协作，允许节点在直接无线传输范围之外进行通信。路由是从网络的一个站到其他站交换信息的过程。由于移动的ad-hoc网络的动态拓扑结构、移动的主机、分布式环境、低带宽、低功耗等特点，其路由协议需要采用与现有Internet协议不同的方法。根据路由发现的时间和方式，Ad Hoc路由协议可以分为两类：表驱动（主动方案）和按需路由（反应方案）。在表驱动路由协议中，每个节点维护一个或多个包含关于网络中的节点的路由信息的表，而在按需路由中，路由是在需要时创建的。表驱动路由协议包括目的地顺序距离矢量路由协议（DSDV）、网关交换路由协议（CGSR）、分层状态路由协议（HSR）和无线路由协议（WRP）等。按需路由协议包括Ad Hoc按需距离矢量路由协议（AODV）、动态源路由协议（DSR）。
Ad Hoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any centralized administration, in which individual nodes cooperate by forwarding packets to each other to allow nodes to communicate beyond direct wireless transmission range. Routing is a process of exchanging information from one station to other stations of the network. Routing protocols of mobile ad-hoc network tend to need different approaches from existing Internet protocols because of dynamic topology, mobile host, distributed environment, less bandwidth, less battery power. Ad Hoc routing protocols can be divided into two categories: table-driven (proactive schemes) and on-demand routing (reactive scheme) based on when and how the routes are discovered. In Table-driven routing protocols each node maintains one or more tables containing routing information about nodes in the network whereas in on-demand routing the routes are created as and when required. Some of the table driven routing protocols are Destination Sequenced Distance Vector Routing protocols (DSDV), Clusterhead Gateway Switching Routing Protocol (CGSR), Hierarchical State Routing (HSR), and Wireless Routing Protocol (WRP) etc. The on-demand routing protocols are Ad Hoc On-Demand Distance Vector Routing (AODV), Dynamic Source Routing (DSR).
