| 摘 要： | 以往无线传感器网络中的媒体接入控制协议主要针对静止网络。当存在移动节点时。协议性能会大幅度降低。对存在移动节点的无线传感器网络中的媒体接入控制协议进行了性能分析，提出了改进算法。仿真结果验证了算法的有效性。最后给出了一种适合移动节点较多的场景的无线传感器网络媒体接入控制协议。

| Abstract: | Former Media Access Control(MAC)protocols for Wireless Sensor Networks(WSNs)are mainly for stationary networks.In the networks where mobile nodes exist the performance will degrade badly.In this paper the performance of MAC in mobile WSNs (mWSNs)is analyzed and improvable algorithms are presented.Simulations validate the effects.A new MAC protocol also is presented for the scenario with more mobile nodes. |
