For the limitation of the network resources, to support real-time service in mobile ad hoc networks is challenging, especially for the delay sensitive voice sessions. Firstly, the delay spike phenomenon is described and analyzed in detail in this paper. Then, to alleviate its impairment on the voice quality, based on the prediction of delay spikes, a new source rate adjusting mechanism is proposed,...
Multimedia applications have been the key driving force in converging fixed, mobile and IP networks. A major hurdle in the realisation of this convergence is obtaining Quality of Service from a heterogeneous, best-effort service network. Interactive voice requires strict bounds on delay, jitter and packet losses, video adds significant bandwidth requirements to the network, while Internet only makes...
We propose an efficient mobile multimedia communication protocol, mobile terminal software platform and mobile VoIP application for IP-based convergence networks. The proposed mobile multimedia communication protocol is called as ST-MRSVP (split tunnel based mobile resource reservation protocol) which integrates split tunnel based mobile IP and RSVP. Since mobile multimedia terminal platform should...
