Abstract:In modern communication, wireless technology has been applied into all aspects of our lives. Wireless nodes can play better role in the application of various industries unable to arrive at, the area that the wired communication can not reach, or the poor environment. Wireless micro node is the main form of the application of wireless sensor networks in recent years. Wireless micro node has the Characteristics of ultra low power consumption, small volume, working in a variety of harsh environment ,whitch make it possible that the application of the wireless micro node will get more and more extensive.

　　In this paper, it designs and realizes a wireless communication protocol that has the character of real-time stability with low energy consumption whitch based on CC1101 chip made by TI comply for the wireless application problems on traffic detection field. This paper briefly introduces the problem of forming the protocol packet format, the determination of transmission error detection and data processing, such as synchronization of transmitter and receiver .It discribes detaily the analysis of the principle of energy-saving and the anti-collision in the use of CC1101. It also describes the processing of communication between the data packetand implementation of sending and receiving protocol, and the hardware and software design method using 89C52 microcontroller wireless communication. Finally ,it shows the application of wireless communication protocol through an example.

　　　近年来由于微电子技术、计算机技术和无线通信技术的进步，使得大量低功耗、多功能、低成本、对等通信的无线节点的问世成为可能。有多个节点共同构成的网络吸引了大量学者的兴趣。在环境监测、交通运输、医疗等领域的科学研究中得到广泛的应用。

　　　无线节点通信的节点通常配备一个或多个不同的传感器，用于完成采集物理数据的任务。同时在节点上还配置了存储器、微处理器、执行器、电源和射频收发器等。与传统的无线节点不同，现在的无线节点体积小、价格便宜，但是节点的能量相对较弱。除此之外，现代无线节点常用电池来供电，并且常常工作在恶劣的环境或是工作在敌方区域，不能提供电池补给或更换，因而电源也是约束无线节点的一个重要因素。

　　　无线节点通信的研究目标是满足上述约束条件的同时完成指定的任务。引入新的设计概念、开发或改进现有协议、开创新的应用领域、开发新的算法，都将成为无线节点通信的热点。
