When supporting both voice and TCP in a wireless multihop network, there are two conflicting goals: to protect the VoIP traffic, and to completely utilize the remaining capacity for TCP. We investigate the interaction between these two popular categories of traffic and find that conventional solution approaches, such as enhanced TCP variants, priority queues, bandwidth limitation, and traffic shaping...

Typically, VoIP traffic is deployed as best-effort traffic over Internet links. This voice traffic lacks effective and scalable end-to-end congestion control. We propose a new VoIP congestion control scheme called Voice-TFCC (voice TCP-friendly congestion control), that tries to keep the transmission protocol overhead to a minimum while maintaining a TCP-friendly throughput. Voice-TFCC adjusts packet...
Low-cost wireless routers are changing the way people connect to the Internet. They are also very cheap, albeit quite limited, Linux boxes. These attributes make them ideal candidates for wireless mesh routers. This paper presents a minimally invasive mechanism for redundant multipath routing in kernel-space to achieve high reliability with high throughput in a mesh network. This service is essential...
