Interference of 802.11B WLAN and Bluetooth: Analysis and Performance Evaluation

IEEE 802.11 and Bluetooth, these two operating in the unlicensed 2.4 GHz frequency band are becoming more and more popular in the mobile computing world. The number of devices equipped with IEEE 802.11 and Bluetooth is growing drastically. Result is the number of co-located devices, say within 10 meters, grown to a limit, so that it may causes interference issues in the 2.4 GHz radio frequency spectrum. Bluetooth supports both voice synchronous connection oriented (SCO) data and asynchronous connection less (ACL) packets. In this paper, we investigate the interference issues of 2.4 GHz frequency band. In addition, this paper presents a new Bluetooth voice packet Synchronous Connection Oriented with Repeated Transmission (SCORT) scheme to optimize the performance of 2.4 GHz frequency band by minimizing the interference between Bluetooth and 802.11 wireless networks. For the sake of experimental verifications, we provide a comprehensive simulation results using Matlab Simulink

IEEE 802.11 & Bluetooth Interference: Simulation And Coexistence

IEEE 802.11 and Bluetooth, these two operating in the unlicensed 2.4Ghz frequency band are becoming more and more popular in the mobile computing world. The number of devices equipped with IEEE 802.11 and Bluetooth is growing drastically. Result is the number of co-located devices, say within 10meters, grown to a limit, so that it may cause interference issues in the 2.4Ghz radio frequency spectrum. Bluetooth supports both voice (SCO) and data (ACL) packets. In this paper we investigate these interference issues and use a new Bluetooth voice packet named synchronous connection-oriented with Repeated Transmission (SCORT) to study the improvement in performance. For the sake of simulation results, we provide a comprehensive simulation results using MATLAB Simulink.http://ieeexplore.ieee.org.libproxy.bridgeport.edu/stamp/stamp.jsp?tp=&arnumber=493912
