Abstract: A kind of special mobility management scheme is proposed for the UAVS Communication Network, in which the location management scheme is based on Hierarchical Call Protocol (HCP), and the handoff management scheme is syncretizing relative signal strength with hysterics and threshold initiation criteria, UAV node’s self controlled emergent handoff decision and guard channel with first-in-first-out queue (GCM-FIFO) channel allocation strategy. After theoretic analysis, graphic performance testing and software simulation, results show that the location management scheme and handoff scheme resoled the problems successfully in the UAVS Communication Network such as high mobility of UAV node, high load of handoff traffic with limited channels and the emergent handoff decision in the event the Relay Plane Node for communication is destroyed.
