Peer-to-peer live video streaming over mobile ad hoc network

ABSTRACT

Peer-to-Peer (P2P) technology has been shown to be effective for content delivery on the Internet. Its applications such as video streaming on Mobile Ad hoc NETwork (MANET) has been explored while the issue of live video streaming on MANET is still a real challenge due to frequent changes in network topology, and the sensitiveness of radio links. To combat these challenges, we propose a novel Cross-Layer And P2P based Solution (CLAPS) that distributes a live video stream using an overlay constructed by the Multicast Overlay Spanning Tree (MOST) protocol. In this solution we have adopted the Multiple Description Coding (MDC) to create multiple video descriptions for a given video stream. CLAPS then distributes pieces to the closest peer which on its turn shares the pieces among the interested peers using the MOST protocol. We compared the performances of the CLAPS with that of the original MOST and we showed that in most of the cases CLAPS substantially increases the continuity index of the video stream and significantly, CLAPS performs better with high mobility and with more than one video stream.
