Lichen Lee, Guixiz Kang, Xidong Zhang, Xiangyi Li, Longfeng Chen An Interference Avoidance Strategy for Zigbee Based WeHealth Monitoring System Lichen Lee, Guixiz Kang, Xidong Zhang, Xiangyi Li, Longfeng Chen Dohwan Kim 2013.05.16

Table of contents WeHealth Interference problem Experiment Interference avoidance strategy conclusion

What is WeHealth? Wireless electronic Healthcare Zigbee star topology Interference from the other wireless equipment

WeHealth monitoring system There are two mode for the sensors to transmit data, normal monitoring mode and emergency monitoring mode.

Interference problem Zigbee WiFi 2.4G ISM band, 16 channel(11 ~ 26) 3MHz bandwidth, 5MHz channel spacing WiFi 2.4G ISM band, 22MHz bandwidth

Interference problem Collaborative approach Non-collaborative approach Central controller can monitor the signal of zigbee and wifi. They have good effect on in-system interference. But they can do nothing to the out-system interference. Non-collaborative approach They base on the channel detection and performance measurements. They consist of interference avoidance algorithm, transmission power control, and so on.

Experiment Zigbee chip of TI CC2530 The transmission power : 0dBm The transmission rate : 10packets/s

Experiment D1 : 3m, D2 : 5m, D3 : 3m WiFi channel : 5

Experiment Zigbee channel : 16 the threshold for CCA : -77dBm If D2 < 12m, the WiFi signal power is -75dBm If D2 < 8m, the RSSI of zigbee is -55dBm and the WiFi signal power is -65dBm

Interference avoidance strategy

Interference avoidance strategy Channel estimation algorithm Zigbee interfered channel The interference degree of zigbee channel

Result

Conclusion By using proposed interference avoidance strategy, monitoring sensor can detected and estimated the interference. The coordinator estimated the interfered degree of all the zigbee channels using the proposed algorithm.
