摘　　要：本文针对目前无线传感器网络中传统MAC协议在动态性、低时延方面的不足,在前人研究的基础上,提出一种基于分簇的自适应AMAC协议。该协议将簇分为簇首节点和簇内成员节点,簇内成员节点可以根据自身的状态向簇首节点提出时隙申请,簇首节点对这些申请信息进行仲裁,从而及时调整时间帧的长度,使其能更符合当前网络的负载情况和拓扑结构。通过仿真实验验证,AMAC协议在对实时性、移动性要求比较高的无线传感器网络中性能明显优于其他MAC协议。Taking account of the drawbacks in dynamicity and low latency of the existing MAC protocols for wireless sensor networks,an adaptive AMAC protocol based on clustering was put forward.In this protocol,every member within a cluster could apply to the cluster head for slot according to its state.The cluster head arbitrated this application information,and then adjusted the frame time size in time to make it more suitable for the topology and traffic load of current network.The simulation result show that AMAC outperforms other MAC protocols in the real-time and mobile wireless sensor networks.
