摘　　要：针对在分簇结构的Ad Hoc网络中簇间路由使用传统的按需路由协议时产生通信链路不稳定,负载不均等问题,提出一种新的基于分簇结构的Ad Hoc网络簇间路由协议。首先,针对分簇结构的Ad Hoc网络使用传统的按需路由协议时的缺陷设计一个新的路由度量,该路由度量综合考虑了节点间的稳定性以及节点负载,根据此路由度量设计了多路径链路稳定路由协议。其次,描述了该协议的路由应答的过程,通过路由应答获取不同路径的拥塞程度信息为各个路径合理的分配负载,达到多路径并行传输和网络负载均衡的目的。最后,描述了该协议的路由维护过程,通过路由的维护机制动态调整不同路径的负载。仿真结果表明,提出的路由协议有效地提高了网络吞吐量,降低了端到端传输时延。Aiming at the problem of unstable communication link and unequal load when traditional on-demand routing protocol is used for inter-cluster routing in Ad Hoc networks with cluster structure,a new inter-cluster routing protocol based on cluster structure is proposed.First of all,a new routing metric is designed for the defect of traditional on-demand routing protocol in Ad Hoc networks with cluster structure.The routing metric comprehensively considers the stability between nodes and the load on nodes,and a multipath link stable routing protocol is designed according to the routing metric.Secondly,the routing response process of the protocol is described in detail,and the congestion degree information of different paths is obtained through routing response to reasonably distribute the load for each path,so as to achieve the purpose of multi-path parallel transmission and network load balancing.Thirdly,the routing maintenance process of the protocol is described in detail,and the load of different paths is dynamically adjusted through the routing maintenance mechanism.Finally,simulation results show that the proposed routing protocol can effectively improve the network throughput and reduce the end-to-end transmission delay.
