ABSTRACT:
An important challenge in defining the BlueStar architecture is that both Bluetooth and WLANs employ the same 2.4 GHz ISM band and can possibly impact the performance. The interference generated by WLAN devices over the Bluetooth channel called as as persistent interference, while the presence of multiple piconets in the vicinity creates interference referred to as intermittent interference. To combat both of these interference sources and provide effective coexistence, authors proposed a unique hybrid approach of adaptive frequency hopping (AFH) and a new mechanism called Bluetooth carrier sense (BCS) in Blue-Star. AFH seeks to mitigate persistent interference by scanning the channels during a monitoring period. BCS takes care of the intermittent interference by sensing channel before transmission.
