基于DSR的改进型综合源路由协议

在无线Mesh网络中,动态源路由(Dynamic Source Routing,DSR)协议是一种广泛应用的协议,其路由的建立与维护都从源节点发起。然而,由于DSR协议在路由发现与建立的过程中存在局限性,因此仍需要进一步研究。基于DSR协议通过引入一种综合了路径负载率、时延和跳数的负载均衡机制,并加入能量状态监控和多径路由,提出了一种改进型综合源路由协议(Improved Comprehensive Multi-path Source Routing,ICMSR),能够更好地实现网络负载均衡,节约网络能源,提升网络性能。最后,使用Opnet仿真验证了算法的有效性。仿真结果表明,改进协议在网络生存时间、分组投递率、端到端时延和网络吞吐量等性能指标上,相较于现有DSR协议都有较大的提升。

Improved Comprehensive Source Routing Protocol based on DSR

In a wireless mesh network,the Dynamic Source Routing(DSR)protocol is a widely used protocol,and the establishment and maintenance of its routes are initiated from the source node.However,due to the limitations of the DSR protocol in the process of route discovery and establishment,there is still room for improvement.Based on the DSR protocol,a load balancing mechanism combining path load rate,delay,and hop count is introduced,and energy state monitoring and multipath routing are added.At the same time,an improved comprehensive source routing protocol(Improved Comprehensive Multi-path Source Routing,ICMSR)is proposed,which can better achieve network load balancing,save network energy,and improve network performance.Finally,the effectiveness of the algorithm is verified by using Opnet simulation.Simulation results indicate that the improved protocol has greatly improved the performance indicators of network survival time,packet delivery rate,end-to-end delay,and network throughput compared with existing DSR protocols.
