Dynamic clustering schemes of ZigBee networks in the presence of WLAN interference

As ubiquitous networking emerges, ZigBee devices among various communication devices in the PAN have attracted considerable attention in sensor networks. However, ZigBee devices may significantly experience severe degradation in the presence of WLAN. We propose dynamic clustering schemes of ZigBee networks in order to avoid the WLAN interference. Simulation results show that our proposed scheme is more effective than the conventional scheme.
