Optimization Technology of Concurrent Routing Transmission in FANET

The formation of UAV self-organizing network, called flight ad hoc network (FANET), can provide reliable and real-time network communication for UAV group, which is the development trend of UAV technology and has a very wide application prospect. However, due to the rapid speed of node movement in the UAV network, there will be packet loss in the transmission process, which will reduce the transmission reliability. Therefore, an improved AOMDV protocol based on channel state is proposed in this paper, which makes the data packets transmit in multiple paths simultaneously and improves the reliability of the transmission process. Combined with branch and bound method, each path is optimized to effectively reduce the negative impact of channel fading in the node transmission process, improve the end-to-end throughput, then improve the effectiveness of the overall transmission process. Simulation results show this method can improve the packet delivery rate and end-to-end throughput.
