Abstract:  Due to the strong mobility of nodes, the possibility and randomness of network holes are increasing in UAV network. The general geographic assistant routing protocols often fail to satisfy the demand of the network.  A sectional optimization mechanism based on packet feedback is proposed. This mechanism sets segment points based on the route forwarding strategy,  optimizes the detour path part, and guarantees to respond to the existing network holes or optimize a new network hole duly. Considering the actual situation of the UAV cruise capability, comprehensive criteria is provided for selection of nodes according to the actual application requirements. The simulation shows that compared with the GPSR algorithm and BOPF algorithm, the proposed algorithm can optimize the transmission path, reduce end-to-end delay and improve network performance.
