Abstract :
We propose a new cooperation mechanism, denoted by cooperative channel segmentation (CCS), between IEEE 802.11 WLANs and Bluetooth based WPANs, which operate in the 2.4 GHz ISM band. The CCS avoids false detection of WLAN carrier sense, which usually happens when WLAN and Bluetooth antenna are nearly deployed. In CCS, WLAN and Bluetooth system share the mutual interference channel information and devices operation channels between Bluetooth and WLAN. We evaluated the performance of CCS by simulation, and the simulation result showed that the performance of CCS is better than legacy cooperation mechanisms.
