Özet
An Ad hoc Network provides quick and easy networking under circumstances that require temporary network services or when cabling is hard to deploy. It can be adopted as a solution for coverage in rural areas, disasters and military applications. Ad hoc Networks can be used to extend the range of wireless service coverage. Providing quality of service in ad hoc networks is an extremely challenging task, due to several factors like the unrestricted mobility of nodes, dynamically varying network topology, and other ones. There are two approaches to audio and video transmission: single stream and multi stream. The former transmits a single transport stream of interleaved audio and video, while the latter treats the two media as separate transport streams. In this paper, we describe a novel scheme for audio and video transport over wireless ad hoc networks. The main idea of this work is based on selecting special nodes of transferring path as proxy nodes. In each of every transmitting routes only one node will select as audio & video proxy nodes based on an agreement between sender and receiver or network traffic status. The duty of these nodes is to receiving and recognizing audio and video streams, buffering of favorite streams and if possible managing errors locally. Choosing these nodes and employing them at network add to increasing network life time will result in reduced end to end delay between sender and receiver.
