摘　　要：通过分析无人机节点运动速度与能量状态,实施MPR选举前就先预处理高速低能量的节点,在同一意愿值条件下重新以加权方式计算出节点能量消耗,由此获得最优的MPR节点集。仿真分析得到:当节点达到很高的移动速度时,ODSR协议表现出很强的延时抖动现象,文中协议则几乎不会出现延时抖动,达到了比DSR协议以及原协议更小的时延。各模块利用消息发送的方式来完成初始化过程,此时的吞吐量等于0,之后通过能量消耗MPR得到的OLSR协议形成了比OLSR原协议更大的吞吐量,使网络运行达到了更高的稳定性。所有节点都拥有0.5J的初始能量,剩余能量逐渐降低,OLSR协议可以形成比DSR协议更低的能量消耗,从而有效保障了网络节点的生命周期。By analyzing the moving speed and energy state of uav nodes,the high speed and low energy nodes are preprocessed before the implementation of MPR election,and the energy consumption of nodes is calculated in a weighted way under the same intention value,so as to obtain the optimal MPR node set.The simulation analysis shows that when the node reaches a high moving speed,the DSR protocol shows a strong delay jitter,while the OLSR protocol shows almost no delay jitter,achieving a smaller delay than the DSR protocol and the original protocol.Each module completes the initialization process by sending messages,and the throughput at this point is equal to 0.Later,the OLSR protocol obtained through energy consumption MPR generates a higher throughput than the original OLSR protocol,making the network run with higher stability.All nodes have an initial energy of 0.5 J,and the remaining energy gradually decreases.OLSR protocol can form a lower energy consumption than DSR protocol,thus effectively guaranteeing the life cycle of network nodes.
