Abstract :
Due to advantages in enough number of channels and favorable bandwidth, 2.4 GHz ISM band is used as the most prevalent band for the IEEE802.15.4 LR-WPAN. However, there are an increasing number of other devices and systems which may interfere with the IEEE 802.15.4 communication. Therefore, the coexistence issue is one of the most critical challenges for the IEEE 802.15.4. In this paper, we propose an Adaptive Multi-Channel Utilization scheme (AMCU), to enable a WPAN to coexist with other interfering systems. By utilizing multiple channels dynamically, it is possible that an interfered device or coordinator is recovered quickly, avoiding interference during run time as well as during association stage. In addition, in normal state, each device maintains very low duty cycle as in the standard.
