摘要:
在无线传感器网络中，MAC协议决定着网络的信道分配，对网络的性能有很重要的影响。目前已研究出多种S-MAC协议，其中S-MAC协议是一种典型的无线传感器网络MAC协议，但此协议存在一定缺陷，无法更好地适应传感器网Jj络多变的特点。针对该问题，在S-MAC协议的基础上，结合了自适应退避窗口和根据节点队列长度预测流量的思想，提出了一种新的协议-Q-MAC协议，并达到了较为理想的预测效果。经NS2仿真验证，此协议在平均延迟、吞吐量、能量消耗方面较S-MAC协议有了显著提高
Abstract:
The network channel allocation depends on the medium access control （MAC） protocol in wireless sensor network,and MAC protocol has a significant impact on network performance. At present have various MAC protocols, among them the S-MAC protocol is a typical MAC protocol for wireless sensor network, but this protocol has some defects, so it can not adapt to the changing sensor network. According to this pmblemiand considering the functions of adaptive backoff window and the thought of forecasting data flow according to the node＇s length of queueing, a new MAC protocol （ Q-MAC protocol） is proposed based on S-MAC, which achieves the better pre diction result. And compared with S-MAC protocol,this protocol has improved a lot in the average delay of packets,the throughput and the energy consumption by NS2 simulation
