摘　　要：车载自组织网络、无人机自组织网络中节点高动态运动、网络拓扑变化频繁、链路维持时间短,使得传统的移动自组织网络路由协议不能适用.为了满足高动态自组网的需求,改进优化链路状态路由协议,引入移动预测机制.首先,在邻居发现过程中加入节点的位置和速度信息;其次,在中继选择时考虑邻节点的距离,选择不易中断的链路;然后,利用NS3进行仿真,结果表明,改进的优化链路状态路由协议提高了数据成功接收率,降低了端到端平均时延;最后,通过实物平台进行验证.The nodes in vehicle ad hoc networks(VANETs)or flying ad hoc networks(FANETs)have high mobility characteristics.The network topology changes frequently and the time of maintaining communication link is short.As a consequence,the network routing algorithms,which have been designed for traditional ad hoc network,fail to apply.To meet the requirements of high dynamic ad hoc networks,the optimized link state routing(OLSR)protocol is modified by adding a mobility prediction mechanism.Firstly,the position and speed information are added in neighbor discovery phase.Secondly,the distance between neighbors is considered in the relay selection phase,and the link that is not easy to interrupt is selected.Thirdly,the NS3 tool is used to simulate.The simulation results show that the modified OLSR could significantly increase the performance in data packet delivery radio and end to end delay.In the end,the proposed routing protocol is verified in the physical platform.
