    摘要: A method of video distribution within a peer-to-peer network. Once the video has initially been downloaded from a server, various fragments of it reside on various peers of the network. At the location of each fragment, the peer which stores it preferably also carries pointers to preceding-fragment, following-fragment, and same-fragment locations. This provides a list-driven capability so that, once a user has attached to any fragment of the program, the user can then transition according to the previous-fragment and following-fragment pointers to play, fast-forward, or rewind the program.

    摘要: A system and method for integrating infrastructure and ad hoc wireless networks. In one example embodiment, a plurality of nodes and access points exchange beacons and route replies which are forwarded by intervening nodes. Nodes determine whether to switch access points based on cost values contained in the received beacons. Intervening nodes store routes with weights to the source node, such that the access points maintain weights to every node in their zones.

    摘要: A system and method of integrating IP multicasting with application layer multicasting for media streaming. The proposed approach teaches forming an overlay P2P tree using a scalable protocol. New node either detects an existing IP multicasting island to join or forms a new one. Ingress node of each island is adaptively elected and streams media to nodes in its island via IP multicasting, while getting the media from its parent node via traditional unicast to achieve much lower end-to-end delay and link stress.

    摘要: Systems and methods for collaborative streaming among mobile terminals. Periodically, the mobile terminals may pull a portion of the data stream from a content provider coupled thereto over a primary channel and distribute the pulled data to neighboring mobile terminals, possibly including other mobile terminals pulling portions of the data stream from the content provider and passive mobile terminals that are only receiving pulled data. By transferring data over the secondary channel, the cost to any one terminal to receive the data stream is reduced.
