Evom: a software based platform for voice transmission and quality assessment over wireless ad-hoc networks

Published: 23 October 2007 Publication History

Abstract

Transmission of digital interactive voice over ad-hoc networks is a challenging task since these networks exhibit challenging operational conditions such as mobility of all nodes, frequent session loss, random loss, energy consumption, etc. In this paper we present, EVOM, a software-based platform. EVOM (Evaluation of Voice over MANET) is designed to assess objectively the perceived quality of transmitted voice traffic over a wireless Mobile Ad-hoc NETwork (MANET). This framework uses the Real-time Transport Protocol (RTP) to build an adaptive voice application over a MANET. It also implements voice activity detection (VAD) and several playout algorithms. It provides implementation of advanced methods to assess objectively both the listening and conversational quality as perceived by real users. The used methods combine adequately the PESQ (Perceptual Evaluation of Speech Quality) algorithm and the E-Model approach and include the effect of variable nature of network state. EVOM can be used to evaluate new codecs as well as new playout algorithms and their robustness in a MANET. In addition, it can be used to develop new models representing equipment impairment of VoMANET. Moreover, it can be used to tune parameters of the algorithms involved to specific mobility scenarios and nodes density in order to achieve the best performance.
