The low-rate wireless personal area network（LR-WPAN） is defined by IEEE802.15.4 standard which targets at low energy consumption,low-rate transmission and low cost,suitable for individuals or households within the scope of the lowspeed interconnection between different devices.LR-WPAN has much similarity with wireless sensor network,so it is used as a communication platform for wireless sensor.Based on the analysis of LR-WPAN,wireless sensor network is realized.%IEEE 802.15.4标准是针对低速无线个人区域网络（low-rate wireless personal area network,LRWPAN）的无线通信标准。该标准把低能量消耗、低速率传输、低成本作为重点目标,旨在为个人或者家庭范围内不同设备之间的低速互连提供统一标准。由于IEEE802.15.4标准定义的LR-WPAN和无线传感器网络存在很多相似之处,所以把它作为无线传感器的通信平台。在分析LR-WPAN的基础上,实现无线传感器网络的组网设计。
