摘要 文章提出一种新的无线传感器网络MAC协议AMAC。AMAC是对S-MAC的扩展,克服了S-MAC采用固定竞争窗,无法适应网络负载变化的缺点。为不影响协议休眠激活周期的建立,文章提出固定竞争窗加p坚持的退避算法,当退避计数器减为零时,节点不是立即发送数据,而是以最优概率p发送。为确定p值,又推导出使平均发送能耗最小的p与活动节点数的关系,同时提出了活动节点数估计算法。最后通过仿真验证了AMAC协议的自适应性和能量有效性。 In this paper, AMAC, a new Medium Access Control protocol for wireless sensor network is proposed. AMAC protocol is an extension of S-MAC, which overcomes the shortcoming of S-MAC. S-MAC protocol employs a fixed contention window, and when the number of nodes change, its performance would be reduced. In order to set up duty cycle expediently, a contention window plus p persist backoff algorithm is proposed, when the backoff counter decrease to zero, node transmits data packets according to a best probability p rather than transmits data packets immediately. In order to confirm probability p, the relation between p and active nodes is deduced, and a active nodes estimate algorithm proposed. Simulation results in ns-2 proves the adaptability and energy-efficiency of AMAC protocol.
