Optimization of OLSR routing protocol in UAV ad HOC network

According to high-speed mobile nodes in UAV Ad Hoc network to bring the network topology changes frequently, link time is short, the network load increasing to bring the link layer congestion, and node energy is limited, and this paper puts forward a new routing protocol of MPEAOLSR (Multidimensional Perception and Energy Awareness OLSR). The node link time, link layer congestion and node residual energy are comprehensive considered in the MPR set selection. Simulation results show that, compared with traditional OLSR routing protocol, the improved MPEAOLSR routing protocol could improve the data transmission success rate and reduce the packet loss rate and end-to-end delay.
