摘　　要：无线传感器网络(Wireless Sensor Networks,WSNs)是一门新兴的无线网络技术。IEEE802.15.4标准作为一种新兴的无线通信协议,以其低功耗、低速率传输和低成本的设计宗旨为无线传感器网络提供了一种很好的解决方案。对IEEE802.15.4标准的相关规定和特点进行了简要介绍,在该标准的基础上针对当前关于能量消耗、GTS调度机制和CSMA/CA协议等方面的研究现状进行了介绍,并做了总结。Wireless sensor network （WSN）is a new wireless network technology. Used as an emerging wireless communication pro- tocol,IEEE802. 15.4 standard provides a good solution for wireless sensor networks by its design of low power consumption,low-rate transmission and low cost. Firstly, this paper introduces briefly the relevant provisions and technical features of IEEES02. 15. 4 protocol. Based on this standard,it analyzes the research status of existing energy consumption, GTS mechanism and CSMA/CA protocol. Finally, this paper comes to a conclusion.
