摘要: 针对无人机自组织网络中节点运动快速且拓扑变化频繁的特点,提出一种优化链路状态预测的路由协议——OLSFR。OLSFR通过对无人机节点运动链路状态进行预测,并定义计算MPR集合的约束性参数以达到路由选路优化和提高性能的目的。仿真实验证明,相比OLSR、DSDV等相关协议,OLSFR能有效改善无人机自组织网络的数据包传递成功率和端到端延时。

Abstract: This paper proposes a new routing protocol named OLSFR to promote the mobile Ad hoc UAV network with high-speed moving nodes and frequently changing topology. The OLSFR protocol forecasts the link state between two mobile nodes. It uses a new constraint parameter in finding the Multi Point Relay(MPR) set to optimize routing choose and improves the integrated performance. Simulation results show that compared with other relative routing protocols such as OLSR and DSDV, OLSFR protocol can get much better integrated performance in the success ratio of data packet delivering and the end-to-end delay.

Key words: mobile Ad hoc UAV network, Multi Point Relay(MPR), link forecast
