无线传感器网络的协同适应休眠介质访问控制协议

无线传感器网络通常部署在不可到达或危险区域，其能量十分有限。因此，无线传感器网络以节约能量和自我配置为主要目标。本文介绍一种为无线传感网络设计的介质访问控制协议S-MAC，它采用公用休眠时间表、通信量自适应唤醒、串听避免、消息传输等几种新技术来减少能耗并支持自我配置，使得在多跳网络中的低占空比操作成为可能。测量结果表明，S-MAC能节约大量能量。

Medium Access Control with Coordinated Adaptive Sleeping for Wireless Sensor Networks

Wireless sensor networks are usually deployed throughout inaccessible or hazardous regions with limited energy resources. Therefore, energy conservation and self-configuration are primary goals for wireless sensor networks. In this paper, a medium access control protocol--S-MAC designed for wireless sensor networks are introduced, it uses a few novel techniques including common sleep schedules, traffic-adaptive wake-up and avoid overhearing to reduce energy consumption and support self-configuration. It enables low-duty-cycle operation in a multihop network. Measurement results show that S-MAC obtains significant energy savings.
