A reconfigurable framework for experimental analysis of single and multi hop WLANs

This paper presents a reconfigurable framework used to analyze the performance of different technologies in WLAN environments. This framework incorporates state-of-art experimentation tools into a single control paradigm that allows an easy reconfiguration and repetition of experimentation trials. The paper describes the main features of the testbed together with some of the technical solutions adopted. Also, an illustrative experimentation case is described, step-by-step, to show the performance of this tool. Specifically this experimentation case studies the performance of VoIP applications across different wireless scenarios. It reveals some patterns of the behaviour of this type of applications that would be difficult to observe in other more specific experimentation platforms.
