针对无人机自组网拓扑结构变化频繁与节点能量有限的特点,提出了一种具有速度与能量意识的OLSR路由协议(SEA-OLSR,Speed-Aware and Energy-Aware OLSR Routing Protocol).SEA-OLSR综合考虑了节点的速度和能量,通过分级设置每个节点的willingness 项来决定节点是否选为多点中继(MPR, Multi Point Relay)节点.OPNET仿真实验表明,SEA-OLSR较经典的OLSR路由协议,提高了网络的稳定性、延长了正常通信时间并且降低了端到端的延时.

A new OLSR routing protocol with speed and energy awareness (Speed-Aware and Energy-Aware OLSR Routing Protocols,SEA-OLSR) is poposed, thus to promote the mobile Ad hoc UAV network with frequently changing topology and limited node energy.The SEA-OLSR protocol comprehensively considers the speed and energy of the node, and by the classified settings of each node's willingness option, determines whether the node is the MPR(Multi Point Relay)node. OPNET simulation results show that, compared with classic OLSR routing protocol, SEA-OLSR routing protocol could improve the stability of the network, extend the normal communication time and reduce the end-to-end delay.
