Compared to media streaming systems which are based on the Client/Server framework, in P2P network, each client receives data and forwards it to others at the same time. Large numbers of clients resource ignored before can be effectively used. The burden on the server will be relieved and the server can provide better quality of

Streaming media over the Internet is booming nowadays.IP multicast and application layer multicast has become the study hotspots.Because of the inherent limitations of IP multicast,it had not put in a large-scale commercial applications. Based on the P2P network of media distribution techniques,ALM has been extensively studied.The function of the multicast is transferred from network layer

Low utilization efficiency of spectrum, which is caused by fixed spectrum allocation scheme, is the bottleneck of wireless communication systems. The Cognitive Radio (CR) technology is proposed by Joseph Mitola and refers to a smart radio that has the ability to sense the external environment, learn from the history and make intelligent decisions to adjust

3D graphics data are more and more widely used in various applications, including engineering design, medical diagnosing and video gaming. In this paper we use the triangle mesh to represent the 3D mesh model, and concentrate on the compression of connectivity and geometry data.As the number and complexity of existing 3D meshes increase explosively, a

Network coding, which generalizes traditional store-and-forward by allowing intermediate network nodes to generate new packets by performing algebraic operations on incoming packets, has shown advantages in many areas of communication and networking. From the beginning, most efforts are paid on the research on single-rate transmission schemes with network coding. However, networks are heterogeneous in general.
