VoIP design and implementation with network coding schemes for wireless networks

Future networks are aiming to hold more interactive services resulting in higher traffic volume, however Voice over Internet Protocol's (VoIP) high network resource allocation is still a handicap. Recent studies on network coding have proved greater throughput performance by combining packets before broadcasting them. This paper presents a design and implementation of a new methodology for VoIP services with the advantages of network coding schemes. VoIP users are connected through a wireless channel to a SIP proxy that linearly combines users data resulting on a throughput optimisation without any loss of voice quality.
