基于脉冲超宽带无线传感器网络的介质访问控制
Medium Access Control for Wireless Sensor Networks based on Impulse Radio Ultra Wideband
摘要：
本文详细描述了基于脉冲无线电超宽带（IR-UWB）物理层（PHY）的无线传感器网络分布式介质访问控制（MAC）协议的性能评估。两个主要类别的媒体访问控制协议已被认为是：时隙和非时隙的可靠性。可靠性基于自动重传请求（ARQ）。性能评估是使用一个完整的无线传感器网络（WSN）的全球移动信息系统模拟器（GloMoSim）上建立的模拟器。首先从时隙大小、重传时延和重传次数等方面讨论了IR-UWB的最佳工作参数，然后从可靠性、时延和功率效率等方面比较了IR-UWB与其他传输技术的性能。
英文摘要：
This paper describes a detailed performance evaluation of distributed Medium Access Control (MAC) protocols for Wireless Sensor Networks based on Impulse Radio Ultra Wideband (IR-UWB) Physical layer (PHY). Two main classes of Medium Access Control protocol have been considered: Slotted and UnSlotted with reliability. The reliability is based on Automatic Repeat ReQuest (ARQ). The performance evaluation is performed using a complete Wireless Sensor Networks (WSN) simulator built on the Global Mobile Information System Simulator (GloMoSim). The optimal operating parameters are first discussed for IR-UWB in terms of slot size, retransmission delay and the number of retransmission, then a comparison between IR-UWB and other transmission techniques in terms of reliability latency and power efficiency.
