应用于城市消防的传感器网络MAC协议
首发时间:2011-12-28
摘要:无线传感器网络MAC协议即传感器节点的信道访问控制协议,位于物理层和网络层之间,对数据传输起着至关重要的作用。设计合理的MAC协议可以提高节点的信道利用率和能量有效性,可以延长传感器网络的生命周期。无线传感器网络是一种面向应用的无线网络,根据实际的应用场景设计的MAC协议才是合理的,文章以城市楼宇消防为应用背景,设计了一种基于轮询的无线传感器网络MAC协议,该协议将能量有效性和延时控制作为重点考虑的指标,并利用NS2对协议进行了仿真分析。

Wireless Sensor Network MAC Protocol for City Fire
Abstract:MAC protocol for wireless sensor network that medium access control for sensor node which is located between physical layer and network layer plays a vital role on the transmission of data. Reasonable MAC protocol can improve the channel utilization and node energy-efficiency and extend wireless sensor network life cycle. Wireless sensor network is an application-oriented wireless networks, according to the actual application of the MAC protocol design is reasonable. The paper designs a polling-based MAC protocol for wireless sensor networks on the background of city fire service which take the control of time-delay and energy-efficiency as a key consideration, and then conducted a simulation using NS2.
Keywords: wireless sensor network city fire MAC protocol energy delay
