Abstract :
Recent studies have shown that low-power ZigBee based wireless sensor networks (WSN) are vulnerable to the interference generated by Wi-Fi nodes. In this study, the effects of energy detection (ED) mechanism in clear channel assessment (CCA) of ZigBee transmitter under 802.11g Wi-Fi interference have been evaluated through experimentation. To improve the performance of ZigBee packet transmission, a preliminary adaptive mechanism is implemented and evaluated in our testbed.
