Design Of Wireless Sensor Network Based On ZigBee And Analysis Of Anti-interference Capability

Wireless sensor network technology is currently the most popular field of study，whichintegrates a wide range of knowledge and applications, promoting the rapid development of thenetworking industry, with great influence. ZigBee technology is very suitable for wireless sensornetworks, due to low rate, low power, low cost, and better scalability,getting a great attention in thefield of research and application.This design, based on the applications of smart house, establishes a wireless sensor network byCC2530, and accomplishes the multi-hop routing and network self-healing capability. Meanwhile,the nodes are configured as temperature, light intensity and gas sensors, with the LED lightingcontrol module. The management platform achieves the environmental information and state oflight, and control the working state of nodes.In terms of system performance, this paper tests the self-healing time of ZigBee sensor network,and the packet loss rate caused by transmission distance, routing, power. Besides, this paper analyzethe frequency interference of WiFi, Blutooth, etc, then puting forward some suggestion inapplication.
