传感器网络多址接入协议的实现

Realization of the MAC Protocol in the Sensor Network

无线传感器网络(WSN)由于其巨大的应用潜力成为近年来研究者们广泛关注的热点问题。WSN中的多址接入协议(MAC-Medium Access Control)决定了各节点是否能够高效的共享信道,因此直接影响到了WSN的性能。文中针对突发业务环境的无线传感器网络实现了一种新型S-MAC协议,详细论述该协议设计中的关键步骤以及对应的策略,并将该算法移植到了传感器节点的开发平台上。最后通过在硬件平台的测试,得到了正确的输出波形。

Because of its huge application potential, the wireless sensor network （WSN） has become a hot topic in recent years. The channel efficiency of WSN depends on the Medium Access Control （MAC） protocol, so the MAC protocol has a direct effect on the performance of WSN. The S_MAC protocol which suits the scene of WSN is introduced in this paper. The designs of and strategies for the communication between sensor nodes are illustrated at length, and this arithmetic has already been realized on the development board. Finally, the waveform results observed from the oscillograph show the success of the realization of the MAC protocol.
