A Novel Schema for Multipath Video Transferring over Ad Hoc Networks

Real-time multimedia transport has stringent bandwidth, delay, and loss requirements. It is a great challenge to support such applications in wireless ad hoc networks, which are characterized by frequent link failures and congestion. Using multiple paths in parallel for a real-time multimedia session (called multipath transport) provides a new degree of freedom in designing robust multimedia transport systems. In this article, we describe a novel schema for multipath video transport over wireless ad hoc networks. The main idea of this work is based on transferring video through two disjoint paths using AOMDV. In each of these paths we use video proxy nodes as video caches. The duty of these nodes is to receiving and recognizing video streams, buffering of favorite streams and if possible managing errors locally.
