摘　　要：针对空战环境的复杂性和无人机网络中节点的高动态运动引起网络拓扑变化快的特点,提出了一种自适应基于位置预测的优化链路状态路由(ALOLSR)协议,当GPS信息可用时,该协议将OLSR协议中的拓扑控制信息代替为本节点的位置和速度信息,通过MPR泛洪使网络中每个节点获知其他节点位置和速度,在路由选择上充分利用节点定位信息选择稳定的链路。利用NS3仿真无人机组网,结果表明,ALOLSR协议提高了网络分组交付率,降低了数据传输时延。To decrease the effect of the complicated aerial warfare environment and the fast changing topology of the highly dynamic nodes in the UVA（unmanned aerial vehicle） networks,an adaptive optimized link state routing protocol（ALOLSR） was proposed.This protocol used the node location and speed information instead of topology control information in OLSR when GPS information was favored.The nodes in the networks received location and speed of the others by MPR flooding.The routing strategy made full use of GPS information to select stable links.Using the NS3 to simulate the UVA networks,the result shows that ALOLSR achieves better performance in packet delivery radio and delay.
