摘要：

为了解决无线传感器网络内部节点干扰和外部Wi Fi网络干扰引起的服务质量下降问题,提出了一种动态多信道MAC协议DM-MAC.首先,通过3次握手机制和分布式计算方法为网络内节点分配初始信道.其次,构造拉丁跳频矩阵,节点根据初始信道号在矩阵中选取对应的跳频序列.在此基础上,利用状态转移图调整每个信道在跳频序列中的位置.当可用信道数量发生变化时,根据信道状态转移图生成新的拉丁跳频序列.最后,利用网络仿真软件NS2对DM-MAC通信性能进行分析.实验结果表明,与Mu CHMAC协议相比,DM-MAC能够有效地降低突发流量传输时内部节点间的干扰,以及外部Wi Fi干扰源对无线传感器网络性能的影响.同时,该协议改善了平均端到端延时和数据延时上限性能指标,提升了网络服务质量.
