Abstract

Efficiency in any wireless sensor based application relies significantly on the medium access control it implements. It is not likely that we will see in the near future a unified MAC protocol for wireless sensor networks that is suitable for all wireless sensor applications. In this context, we propose an event based medium access control (EB-MAC) that is tailored for event based systems. Typically, event based systems are characterized by having long periods of inactivity and short abrupt periods of high data contention when an event is detected. High data traffic is generated simultaneously from all sensors detecting the event to deliver captured data. EB-MAC arranges data transfer dynamically using an election based scheduling technique. When data transfer begins, each sensor at a time starts sending data packets in a contention free environment. The protocol is implemented on MicaZ sensor motes where it showed efficiency in reliability, throughput and energy conservation. The algorithm is compared with an implementation of B-MAC with RTS/CTS on MicaZ where it showed its superiority in throughput and latency.

EB-MAC:无线传感器网络基于事件的媒介访问控制

任何基于无线传感器的应用的效率在很大程度上依赖于它所实现的介质访问控制。在不久的将来，我们不太可能看到适用于所有无线传感器应用的无线传感器网络的统一MAC协议。在这种情况下，我们提出了一个基于事件的媒体访问控制(EB-MAC)，它是为基于事件的系统量身定制的。通常，基于事件的系统的特点是在检测到事件时具有长时间的不活动和短时间的高数据争用。所有检测事件的传感器同时产生高数据流量，以传递捕获的数据。EB-MAC使用基于选举的调度技术动态地安排数据传输。当数据传输开始时，每个传感器一次在无争用的环境中开始发送数据包。该协议在MicaZ传感器节点上实现，在可靠性、吞吐量和节能方面表现出高效率。将该算法与MicaZ上基于RTS/CTS的B-MAC实现进行了比较，结果表明该算法在吞吐量和延迟方面具有优势。
