Performance Optimizations for Deploying VoIP Services in Mesh Networks
In the recent past, there has been a tremendous increase in the popularity of VoIP services as a result of huge growth in broadband access. The same VoIP service poses new challenges when deployed over a wireless mesh network while enabling users to make voice calls using WiFi phones. Packet losses and delay due to interference in a multiple hop mesh network with limited capacity can significantly degrade the end-to-end VoIP call quality. In this paper, the authors discuss the basic requirements for an efficient deployment of VoIP services over a mesh network. The authors present and evaluate practical optimizing techniques that can enhance the network capacity, maintain the VoIP quality and handle user mobility efficiently.
