摘　　要：链路状态路由协议(optimized link state routing,OLSR)中的多点中继(multi-point relay,MPR)节点存在运动速度过快和能量较低的问题,进而会增大节点负担和缩短网络寿命。为此设计了一种面向OLSR的卫星定位精度多点中继机制评估方法,并开展仿真分析。研究结果表明:与原协议相比,节点能量消耗MPR选举生成协议性能更佳,有利于网络运行稳定性。各节点测试时间为10 s时能量均为0.052 J,剩余能量在测试阶段不断下降,网络节点的生命周期可得到有效保障。该研究有助于卫星定位精度,对保证网络信号的传输效率具有一定的意义。Multi-point relays(MPR)nodes in the optimized link state routing(OLSR)protocol suffer from excessively fast motion and low energy,which increases node burden and shortens network lifetime.Therefore,an OLSR-oriented multi-point relay mechanism evaluation method for satellite positioning accuracy is designed and simulated.The results show that compared with the original protocol,the MPR election generation protocol with node energy consumption has better performance,which is conducive to the stability of network operation.When the test time of each node is 10 s,the energy is 0.052 J,and the remaining energy decreases continuously during the test stage,so the life cycle of network nodes can be effectively guaranteed.This research contributes to the accuracy of satellite positioning and has certain significance for ensuring the transmission efficiency of network signals.
