Abstract: This talk addresses techniques for enhancing multimedia delivery over mobile ad-hoc networks (MANET) and improve video transmission quality of service. In the first part we focus on multicasting multi-streaming techniques. Dissemination of multicast real time video over the Internet has emerged as an important area of network research. Streaming applications must deal with persistent rate changes to prevent network congestion and avoid overwhelming the client buffer. Therefore, receivers have to be conscious of the network available bandwidth and choose the stream rate appropriately. Here we present a scheme to achieve multicasting multistreaming in MANET.
The second part discusses video caching techniques for MANET. Video caching has been well accepted as viable method to ease the ever growing bandwidth needs, improve the speed of video delivery, reduce the server load, and decrease the client access latency. Here we focus on carefully selecting the nodes to cache the video based on the links reliability, the nodes resources, and the availability to serve other nodes in the network. We discuss caching placement mechanism in an attempt to achieve high network performance by distributing the video streams among the virtual backbone nodes.
