Design and Implementation of Mobile QoS Testbed “MOBIQ” for Multimedia Delivery Services
نویسندگان
چکیده
In this paper, we introduce our mobile QoS testbed “MOBIQ”, which is designed for mobile multimedia services including VoIP (Voice over IP) and audio/video streaming. The key components on this are 1) multiple-reference compression of RTP/UDP/IP headers for efficient media packet delivery on radio links, 2) layer2 combined queueing, which integrates wireless layer2 functionality into an IP-layer queueing model to provide low latency for real-time applications, and 3) QoS (Quality of Service) control utilizing feedback information from a network agent called “RTP monitoring agent” in the face of both network congestion and radio link errors. These components enhance quality of multimedia delivery services in 3G and future mobile networks.

Testbed Evaluation of QoS Routing Enhancements for Mobile Ad Hoc Networks
Mobile Ad hoc Networks (MANETs) are a specific type of wireless network that is infrastructure-less, dynamic and self-organising. There is a growing need for MANETs to support real-time multimedia applications. Most current MANET routing protocols only support best-effort routing. By improving the QoS on MANETs, we can extend the set of multimedia services that can run on the MANET. We propose ...
