Evaluation of wireless links in a hybrid network structure for mobile VoIP services

Abstract

Wireless technologies and new Internet services are making available new kinds of solutions and driving new users needs. In order to guarantee the quality of services provided by these solutions, experimental analysis plays a key role. This article presents an evaluation of a solution to provide voice services for users with mobile devices based on the Internet. We also consider a scenario with different wireless network technologies, more specifically Bluetooth and Wi-Fi. The experimental results were obtained based on a functional mobile VoIP infrastructure, named M-VoIP. Based on the results it was possible to identify the major limitations of the M-VoIP solution.
