Mixed usage of Wi-Fi and Bluetooth for formulating an efficient mobile conferencing application

Abstract

This paper proposes a mobile conferencing system which allows the mixed usage of Wi-Fi and Bluetooth and the performance analysis of it. The performance analysis includes the analysis of interference due to the mixed usage of Wi-Fi and Bluetooth. The objective of this study is to propose a method for formulating the best networking structure of a mobile conferencing system in a given situation. We developed a mobile conferencing system which works for both types of mobile networking methods; they are Wi-Fi for configuring infrastructure networking and Bluetooth for configuring ad hoc networking. We performed some experiments for comparing three mobile networking methods; Wi-Fi only, Bluetooth only, and the mixed usage of Wi-Fi and Bluetooth. These experiments lead us to learn that the mixed usage of Wi-Fi and Bluetooth for a mobile conferencing system can be a good solution for formulating an efficient mobile conferencing application. Our mobile conferencing system can benefit greatly the advantages of both types of networking methods (Wi-Fi for infrastructure networking and Bluetooth for ad hoc networking). Through our experiments, we experienced that the interference of Wi-Fi and Bluetooth degrades the system performance to some degree, however, it occurs randomly and it is tolerable if the application is carefully implemented to avoid the effect of interference. © Springer-Verlag 2004.
