QUALITY OF SERVICE ISSUES IN WIRELESS VOICE OVER INTERNET PROTOCOL

Oladunni Abosede Daramola

Abstract


Voice over Internet Protocol (VoIP) is a significant application of the converged network principle where the voice traffic is routed over Internet Protocol shared traffic networks. VoIP traffic was modelled over wireless network and a simulation of the traffic was transmitted over the network. E-model technique was used to analyze the traffic data and also to rate VoIP QoS parameters.  The result achieved was mapped to the Mean Opinion Scale to determine the Quality of Service of VoIP over wireless networks. The results shows that QoS in the VoIP communications is significantly impacted by these parameters and the impact varies according to the parameters and also the communication aspects selected for the VoIP traffic analysis.

Keywords: VoIP, QoS, E-Model and Mean Opinion Scale
