A Three Layer Multimedia Sharing (TLMS) for managing access right of user in a P2P network is proposed in this paper. The features of TLMS include: 1) a novel DRM scheme for P2P networks, 2) a digital content protection without the need of an on-line server, and 3) low communication and computation cost. In addition to introducing the operation of TLMS model, we also compare its performance and security...
In ad-hoc networks, cooperative diversity is especially beneficial where the use of multiple antennas may be impractical. There has been a lot of work on improving the peer-to-peer link quality by using advanced coding or power and rate allocation between a single source node and its relays. However, how to fairly and efficiently allocate resources among multiple users and their relays is still unknown...
In Mobile Ad hoc NETworks (MANETs), random access and dynamic routing are two critical techniques for mobile nodes to convey information without centralized scheduling. Conventionally, random access and dynamic routing are implemented at the Medium Access Control (MAC) and the network layer, respectively. However, the current MAC protocol Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA)...
