摘要
在无线传感器网络体系结构中,MAC(Medium Access Control)协议是保证网络高效通信的重要协议。无线传感器网络有着与传统无线网络明显不同的性能特点和技术要求。对于很多的MAC层协议而言,吞吐量很大程度上受到了物理信道的利用率和协议开销的限制。这里设计了一种基于一对多拓扑的无线传感器Mac层网络协议。最后,还通过NS-2(Network Simulator 2)仿真并比较该协议与现存无线传感器MAC层网络协议的网络性能。
With the explosive development of wireless sensor network, MAC （medium access control） protocol in the wireless sensor network system structure becomes an even more important protocol in ensuring the efficient communication. Wireless sensor network is significantly different in characteristics and technical requirements from the traditional wireless network. For many MAC-layer protocols, throughput is heavily limited by physical channel utilization and protocol overhead. Based on one-to-multiple topology and link quality, a MAC-layer protocol for wireless sensor network is proposed and designed. Finally simulation with NS - 2 （Network Simulator 2） is done, and the network performance comparison of the newly-proposedMAC-layer protocol with the existing MAC-layer protocol also made.
