摘　　要：针对ZigBee网络调度中存在的问题,提出了一种基于令牌机制的ZigBee网络调度策略,并以实验室已实现的ZigBee模块为硬件平台开发了基于令牌机制的ZigBee网络调度软件,组建了调度试验系统.测试表明,该调度策略有效地避免了同一时段数据包相互竞争带宽,减少了数据之间的相互干扰,提高了信道的利用率,缩短了网络的传输时延.Aiming at the problems existing in ZigBee network scheduling, the paper proposes a scheduling strategy for ZigBee network based on token mechanism, and it has achieved it on the hardware platform of ZigBee module implemented by the laboratory, then constitute the scheduling experiment system. The test results show that,the scheduling strategy has effectively avoided data packets competing bandwidth at the same tine,reduced the interference between data ,thus improved the utilization of the channel and shortened the network transmission time.
