| Abstract: | There is a major challenge for the wireless communication technology due to sharing the 2.4GHz ISM band with Bluetooth and WLAN system.In this paper,it is focused on investigating and analyzing the techniques to mitigate the effects of interference for Bluetooth:Bluetooth Interference Aware Scheduling(BIAS) algorithm and rate scaling algorithm.The performance of TCP in a mixed Bluetooth and WLAN environment is gained from simulation.These results show that above technologies are useful to improve the performance in Bluetooth and WLAN,and can effectively eliminate the interferences in the mixed Bluetooth and WLAN environment. |
