摘要
文中提出一种基于SMAC思想的MAC协议,在SMAC协议中加入功率控制机制,以相邻传感器节点数量来调整发射功率的大小,为不同的相邻传感器节点选择合适的功率等级,建立功率等级表,节点通过查询调度表以最优功率发送数据包;最后通过NS2仿真实验验证加入功率控制机制的MAC协议在节约能耗、降低延迟、提高吞吐量和数据包投递率等方面的优势。
This article proposed one kind of SMAC thought based on MAC protocol, in SMAC agreement to join power control mechanism to adjacent sensor node quantity to adjust the size of the transmitted power, finally through the NS2 simulation experiment to join power control mechanism of the MAC protocol in saving energy consumption, reduce the delay, improve the throughput and packet delivery ratio etc advantages.
