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

Abstract

International audiencePeer-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 strea

Power efficient peer-to-peer streaming to co-located mobile users

“…In [12], the authors show that P2P cooperation can be used to provide near-live TV stream in a resource-constrained mobile environment. In [13], a cross-layer P2P solution is proposed to distribute live video stream over a mobile ad hoc network by multicasting the streaming content over a spanning tree in an overlay network. While most existing work uses the P2P networks to reduce MUs' Internet access requirement [14] and to improve the streaming quality [14], [15], less attention has been paid to the power consumption of the MUs.…”

Survey of cross-layer proposals for video streaming over Mobile Ad hoc Networks (MANETs)

“…Such proposals, constituting 50% of the total, as aforementioned, use adaptation and optimization at the network/transport layers along with upper layers [6,7,8,9]. Niraula et al [6] adopts Multiple Description Coding (MDC) to create multiple video descriptions for a given video stream.…”

A model for mobile voice message service using JAVA ME

“…Research was conducted within the areas of mobile streaming services solutions. The study reveals that although there are various papers on using JAVA ME to developed such solutions within the domain of mobile streaming services [4,5,6,7,8], there is little research focusing on the use of a JAVA ME based solution in Wi-Fi environments using different voice codec for mobile voice streaming. However, the work reported in [4] presents a new system that provides audio messages streamed to mobile phones using RTSP even if formerly the mobile phone does not support this protocol.…”

“…They have developed a system based on JAVA ME framework. [7] Proposes a novel CrossLayer and P2P based Solution (CLAPS) that distributes a live video stream from a source node to a large number of interested mobile nodes on MANET based on the P2P concept. In their solution they have adopted the Multiple Description Coding (MDC) to create multiple video descriptions for a given video stream.…”
