Network coding has been proven with the capability to improve the network bandwidth efficiency for multicast communications. Streaming based IPTV services provided by network operators match the paradigm of using network coding. However, the major research works in the literature focus on the selection of network codes under given routing paths. Few research work jointly considers routing and network...
One of the major challenges for video collaboration lies in video conferencing in low bandwidth and low cost. In this paper we discuss about a server less desktop based video conferencing application that has been built around a highly bandwidth efficient H.264 video compression technology. The proposed solution offers a low cost multiparty video conferencing solution suitable for corporate environment...
P2P technology offers a promising scalable solution for video-on-demand (VOD) service. Recent studies have found that departure misses are the major cause of server load in P2P-based VOD. Inspired by this finding, this paper addresses the design of bandwidth allocation policy to decrease departure misses and thereby reduce server load further. We first formulate the minimum departure misses problem...
In this paper, we consider a cognitive wireless mesh network where mesh nodes on an unlicensed spectrum make opportunistic access to a licensed spectrum. Since the spectrum of interest is licensed to a Primary User (PU) or network, power management and bandwidth allocation at the mesh nodes should be carefully picked out such that the interference tolerated at the PU does not exceed a predefined threshold...
Computer network is an important phenomenon for digital information world. Computer network having the various problem due to more demand such as congestion control security, reliability, scalability, fairness etc. Multicast service helps computer network to flow information from one end to another end. In this paper, we provide BDQP approach to minimize the congestion control. NS-2 result shows,...
