基于链路监视的移动自组网路由策略

Link Monitoring Based on Routing Strategy for Mobile Ad Hoc Networks

针对DSDV、AODV、ZRP、LAR等移动自组网路由协议随着节点数量规模增大导致全网路由开销激增的问题,设计提出一种基于链路状态监视的自组网路由策略。该策略以降低路由开销信息的冗余度和链路状态精确反馈为出发点,首先,基于监视能力值竞选产生监视节点,其次,由监视节点通过监视链路对全网链路状态进行监视,精确获取全网拓扑信息,最后,全网其余节点根据实际需要向监视节点查询通向目标节点的路由信息。仿真实验验证了该路由策略的有效性和可行性,结果表明,在移动自组网节点数量规模较大时,该路由策略与传统路由协议相比,能够显著减小移动自组网路由开销。

Aiming at the problem that MANET routing protocols such as DSDV,AODV,ZRP,LAR cause the surge of routing overhead of the whole network with the increase of the number and scale of nodes,a MANET Routing Strategy Based on link state monitoring is designed and proposed.The strategy is from the point of view by reducing the redundancy of routing overhead information and accurate feedback of link state.Firstly,the monitoring node is selected based on the monitoring capability value,and then the monitoring node monitors the link state of the whole network through the monitoring link to accurately get the topology information of the whole network.Then,the remaining nodes of the whole network can query the routing information to the target node from the monitoring node.Simulation experiment shows that the effectiveness and feasibility of the routing strategy.The results show that when the number of nodes in MANET is large,the routing strategy can significantly reduce the routing overhead of MANET compared with traditional routing protocols.
