Directional networking low-overhead routing method

The invention discloses a directional networking low-overhead routing method, and belongs to the field of ad hoc network routing protocols. On the basis of an existing routing protocol, aiming at the problem of overhigh overhead under a directional networking condition, a routing packet structure is reasonably designed, a local routing result is used for replacing link connection condition information of each node, and the transmission control packet length of each node in a link for establishing a route is reduced. And meanwhile, each node actively updates the local network state, so that the route updating ways are increased, the route convergence speed is improved, and meanwhile, the route loop problem can be avoided. 本发明公开了一种定向组网低开销路由方法，属于自组网路由协议领域。本发明基于现有路由协议，针对定向组网条件下开销过高的问题，合理设计了路由分组结构，将本地路由结果替代各节点链路连接情况信息，减少各节点为建立路由在链路中传输的控制分组长度。同时，各节点主动更新本地网络状态，增加了路由更新途径，提高了路由收敛速度，同时能够避免路由环路问题。
