Seamless IP mobility protocols like Fast Mobile IPv6 (FMIPv6) requires the knowledge of candidate access routers, to which the mobile node will hand over its connection to, well in advance while the mobile node is still connected to its current AR. The candidate access router discovery (CARD) protocol is one such protocol that provides the identity and capabilities information of the candidate access...
From a network perspective, the major challenge in providing seamless connectivity whilst maintaining the required level of QoS to users results from the negative interactions that occur between mobility and QoS. These interactions, particularly those of mobility and QoS, have been the subject of much research. In this paper, we discuss the various approaches that have already been taken to combine...
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...
