无线传感器网络FreakZ协议栈分析与实现

摘要

Wireless sensor network ZigBee protocol stack products are expensive and source code is closed,the functions and interface structure in each level of the open source FreakZ protocol stack are analyzed.FreakZ protocol stack is tested by mini6410 embedded development board and CC2530 wireless network card to build a wireless sensor network.Experimental result shows that the network built by FreakZ protocol stack has 50 ms single-hop delay and can get through with data col-lection and remote control functions in the resource-constrained embedded system.%针对当前无线传感器网络ZigBee协议栈产品价格昂贵且源代码封闭的问题,分析了代码开源的 FreakZ 协议栈各个层级实现的功能和接口结构,并通过 mini6410嵌入式开发板和CC2530无线网卡对 FreakZ协议栈进行了组网测试。测试结果表明,FreakZ协议栈构建的网络单跳时延约为50 ms,可在资源受限的嵌入式系统中实现数据采集和远程控制功能。
