Abstract :
The low-power, low-rate ZigBee/IEEE 802.15.4 wireless sensor network (WSN) is vulnerable to the interference from a collocated wireless local area network (WLAN), which operates with considerably higher power in the same 2.4GHz Industrial, Scientific, and Medical (ISM) band. In this paper, a novel and effective Interference Aware Adaptive Clear Channel Assessment (IAACCA) technique is proposed to countermeasure the presence of interference with consequence to improve the performance of packet transmission between ZigBee nodes. The performance evaluation has been done through experimentation performed on a testbed implemented by the authors.
