Abstract—The wireless local area network (WLAN) and wireless personal area network (WPAN) operates ISM band. Spectrum sharing within the similar network can be established by MAC protocols. In heterogeneous networks, the coexistence between WPAN and WLAN has (e.g., ZigBee and Wi-Fi) a difficult problem. The established MAC protocols are unsuccessful in dealing with the different broadcast-power levels, asynchronous time-slots, and unsuited PHY layers of such varied networks. Moderate-to-high Wi-Fi traffic will degrade the performance of synchronized ZigBee. To overcome this problem to introduce a method is called Multichannel Clustering Algorithm(MCA). The Multichannel clustering algorithm has inter cluster channel and intra cluster channel. The Multichannel Clustering Algorithm reduces the collision between WLAN and WPAN devices. The Multichannel Clustering Algorithm will improve throughput and high level interference is also negligible.

Keywords— 802.11, 802.15.4, coexistence, Heterogeneous networks, software MATLAB, Wi-Fi, ZigBee.
