Predictive Channel Scanning And Switching Algorithm For The Coexistence Of Ieee 802.15.4 And Wifi

Among the coexistence problems for the 2.4-GHz industrial, scientific, and medical (ISM) band, interference between WiFi and IEEE 802.15.4/ZigBee networks in particular has become a dominant problem because of the wide installation of WiFi access points (Al's). This paper proposes a predictive channel scanning and switching (PCSS) algorithm that efficiently avoids WiFi interference. In this PCSS algorithm that is based on an IEEE 802.15.4e-2012 multi-channel communication network, each device rapidly senses the interference and switches the channel. This paper evaluates the performance of PCSS by comparing it with existing methods and shows that PCSS is superior.
