摘要/Abstract

摘要：

在无线传感网中，接收机往往处于随时准备接收信息状态，因此节能是一个重要问题.
该文提出一种降低功耗的硬件结构和软件协议联合优化策略，分析了无线收发机节能的关键因素，提出一种简易实用的无线唤醒通信协议，设计了一种低功耗无线收发机.实测结果表明，所设计的无线接收机功耗比传统设备降低10倍以上，达到了实用要求.

Abstract:

Power consumption is a serious challenge to designers of RF transceivers for use in distributed wireless sensor networks since the transceiver must always be powered on for possible incoming packets. In this paper, we propose to combine optimization of the integrated transceiver hardware and the medium access control protocol. By analyzing key factors of lowpower hardware architecture and using a simplified media access control protocol for wake-on-radio, a low power RF transceiver is designed. Test results show that power consumption of the proposed RF transceiver is more than 10 times lower than conventional equipment, satisfying the practical requirements.

Key words: RF transceiver, wireless wake-on-radio, wireless sensor networks
