In this paper, we seek to provide reliable and fast content discovery in peer-to-peer (P2P) video-on-demand (VoD) system to enable user interactivity under peer dynamics. We first identify two characteristics of content discovery in P2P-VoD: real-time constraints and limited local cache. Tapping on these properties, we propose a hybrid content discovery mechanism: SUpeRchunk- based eFficient search...
Wireless technologies, such as 802.11a, provide multiple non-overlapping channels. Effective utilization of the multiple available channels helps to reduce the channel interference so that multiple simultaneous data transmissions can occur and thus increasing network capacity. Initial approach for exploiting multiple available channels is dedicating one interface for each channel. However, this approach...
In this paper, we propose a framework to enhance user perceived quality in a multihomed terminal. Based on the observed media independent handover parameters from all the interfaces, the terminal is made aware of the performance of the different access networks and it can intelligently select the interface to send out the data packets. Several schemes, for the purpose of load balancing, are defined...
Peer-to-peer (P2P) structure is widely applied in multimedia streaming applications to support large number of clients spread all over the Internet. For real-time streaming applications, data arrival time is critical. In this paper, we design a scheduling scheme to manipulate the order of data transmission between peers in order to improve the transmission efficiency in P2P streaming. Simulation results...
