基于洪泛约束的移动自组网多径路由协议

Multipath routing protocol for MANET based on flooding limiting

移动自组网因其网络能够动态重组而广泛应用于紧急救援等场景之中,但其拓扑结构的动态特性导致路由容易断裂,而路由重建将占用较多网络资源。针对该问题提出一种新的基于洪泛约束和多函数度量的多路径路由协议FLMP,利用基于节点移动性的洪泛约束机制,结合局部最优和全局最优思想构建路由,并利用多个路由度量函数选出最优主路由和备份路由用于数据传输。仿真结果表明,FLMP路由协议可以保证数据可靠传输,有效减少路由断裂次数,同时明显地降低路由控制开销。

Mobile ad hoc network(MANET)is widely used in emergency rescue scenarios because of its dynamic network reconfiguration.However,the dynamic topology of MANET causes routes to be easily broken and route reconstruction will occupy more network resources.To solve this problem,this paper proposed a new multipath routing protocol FLMP based on flooding limiting and multiple measurement functions.It uses the flooding limiting mechanism based on node mobility,combines local and global optimal ideas to construct routs,and uses multiple route measurement functions to select the optimal main route and backup route for data transmission.The simulation results show that the FLMP routing protocol can effectively reduce the number of routing breaks,ensure reliable data transmission,and significantly reduce overhead.
