摘要
Unmanned Aerial Vehicle (UAV) network is a wireless network composed of many dynamic nodes. Due to the characteristics of UAV network, in the battlefield, it is easy for UAV nodes to fail and disconnect from other nodes. At this time, it is necessary to quickly delete the failed node from the routing table of all nodes in order to restore the normal routing. The time spent during this period is called the routing recovery time. It is found that for OLSR (Optimized Link State Routing) protocol, when the number of nodes is small, the routing recovery time is mainly related to the expiration time of the neighbor table. When the number of nodes increases, the routing recovery time is mainly related to the propagation speed of the control message. Therefore, this paper proposes a fast routing recovery method based on multi-Antenna to improve the performance of OLSR protocol. Adaptive algorithm is used to dynamically adjust the transmission interval of control messages and the expiration time of neighbor table in OLSR protocol. Simulation results show that the routing recovery time is reduced by using these two schemes.
