The retrieval facilities of most Peer-to-Peer (P2P) systems are limited to queries based on unique identifiers or small sets of keywords. This approach can be highly labor-intensive and inconsistent. In this paper we investigate a scenario where a huge amount of multimedia resources are shared in a P2P network, by means of efficient content-based image and video retrieval functionalities. The challenge...
Recently, much attention has been paid on data-driven (or swarm-like) based live streaming systems due to its rapid growth in deployment over Internet. In such systems, nodes randomly select their neighbors to form an unstructured overlay mesh (gossip-style overlay construction) and then each node requests desired data blocks from its neighbors (block scheduling). To improve the performance, most...
Live media streaming applications are increasing dramatically on the Internet such as IPTV, distance learning, video conference etc. Meanwhile, layered transmission is a promising solution to video streaming over the heterogeneous Internet. This paper presents LSONet, which leverages the advances in both the field of media compression, i.e., layered video coding, and the field of networking, i.e.,...
CoolStreaming is the first protocol which introduces the mesh structure into Application Layer Multicast(ALM) in media streaming application, i.e. each agent may have two or more parents instead of only one parent. However, since the agents in Mesh-based ALM(MALM) are strategy and selfish, the effect of cheating behavior may not be ignored. To solve this problem, we apply the VCG mechanism design...
