摘要
随着信号处理技术的快速发展和新的网络设计思路的出现,多包接收技术在无线传感器网络中的应用为提高网络吞吐量提供了一种新思路。文章在S-MAC协议的基础上,结合了多包接收思想,提出了一种应用于无线传感器网络的新的媒介访问控制协议,并对其吞吐量进行了分析;仿真结果表明,在节点发包速率达到一定值时,新协议可以显著提高无线传感器网络吞吐量。
Along with the fast development of signal processing technology and some new ideas for the network design, the multi-packet reception technology brings forth a new concept to improve the throughput in the wireless sensor networks. This paper, based on S-MAC, takes the multi-packet reception thought and proposes a novel medium access control protocol for applying to the wireless sensor network. The analysis of throughput about this protocol has been given. The simulation result indicates that when node sends packet that attains a certain value, the new protocol may remarkably enhance the wireless sensor network throughput.
