UAVS通信网切换管理方案设计与分析

Design and analysis of handoff management scheme for UAVS communication network

针对UAVS通信网中的切换管理问题,提出了融合滞后余量与门限结合的切换判决方法、基于UAV节点自主决策的紧急切换控制策略和GCM-FIFO信道分配方案的切换管理方案。相关理论分析表明,该切换管理方案解决了UAVS通信网中节点高移动性、切换业务量高但信道数有限以及由于中继机节点遭遇威胁而带来的紧急切换等问题。

This paper proposed a kind of special handoff management scheme for the UAVS communication network, in which the handoff management scheme was 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, results show that the handoff scheme solves 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 in the event relay plane node for communication is destroyed.
