摘要
IEEE802.15.4协议是无线传感网中多采用的一种低速率、低功耗、低成本的无线通信协议。Imote2是Intel公司推出的高集成度的无线传感器平台。文中介绍了Imote2平台以及IEEE802.15.4协议,及网络驱动程序的体系结构,给出了实现IEEE802.15.4的MAC协议过程中的关键函数,还对MAC协议实现中的中断服务响应以及时钟等关键问题进行了描述。并分别对节点的工作性能及组网时节点的性能及损耗进行了测试,给出了系统的性能。结果显示,该种实现方法有效地保证了系统的性能并且可以达到无线传感网组网需求。
The standard of IEEE802.15.4 protocol is a wireless protocol designed for WPAN with low bit- rate, low energy- consuming and low cost. Imote2 is a high integrative wireless sensor platform designed by Intd. This paper introduces the IEEE802.15.4 protocol and the Imote2 platform, and then talks about the architecture of the Linux network driver. Then this paper discusses the most important functions of this driver and gives the performance and the energy consuming results in simple WSN system. The paper also describes several important things such as interrupt response and clock system. The results show that the realization can reach the requirements of WSN system.
