Quality of Service challenges for Voice over Internet Protocol (VoIP) within the wireless environment

摘要

Voice over Internet Protocol (VoIP) is a rapidly growing user technology. Uptake in VoIP technology has significantly increased, especially more recently with the home user moving VoIP away from business dominance. The general population have become accustom to the excellent Quality of Service (QoS) that is now expected from the telecommunications industry both within the landline and mobile infrastructures. QoS within VoIP poses many challenges to be able to compete with the traditional telecom infrastructures. Therefore protocols and standards used to manage today’s evolving networks must change to cope with the present challenges of new technologies. This is especially true if you wish to evolve VoIP practically within the wireless domain. This paper investigates current protocols supporting VoIP services, then identifies current networking technologies to improve their QoS, analysing their viability as a solution
