摘要:

为解决智能楼宇中ZigBee网络与WiFi网络之间的干扰问题,通过采用TI公司的CC2530芯片,设计了一种发射功率自适应调节的无线传感器网络节点。文中主要采用试验的方法对不同环境下的ZigBee节点之间通信的可靠性进行测试,得出通信距离、误包率和接收信号强度指示RSSI之间的关系。利用RSSI作为通信评价因子,根据实际应用环境的变化,自适应地改变ZigBee通信节点的发射功率。经实验测试,只需RSSI值>-51 dBm,便可保证干扰环境下的误包率接近为0。

关键词: ZigBee网络, WiFi网络, 发射功率, RSSI

Abstract:

A wireless data transmission module using CC2530 from Texas Instruments is introduced for wireless communication network nodes based on adaptive adjustment of transmitting power to solve the interference between ZigBee network and WiFi network in the intelligent building.In this paper,the reliability testing based on testing methods is applied in ZigBee nodes in the different environments.The relationship of the communication distance,packet loss rate and RSSI (received signal strength indication) are analyzed.RSSI is used to evaluate the reliability of communication according to the practical application of changes in the environment.ZigBee nodes based on RSSI can adaptively change the transmitting power.The test shows that a RSSI greater than -51 dBm suffices to offer a packet error rate of nearly zero.

Key words: ZigBee network;WiFi network;transmitting power;RSSI
