Scalable Adaptive Group Communication on Bi-directional Shared Prefix Trees

چکیده

E cient group communication within the Internet has been implemented by multicast. Unfortunately, its global deployment is missing. Nevertheless, emerging and progressively establishing popular applications, like IPTV or large-scale social video chats, require an economical data distribution throughout the Internet. To overcome the limitations of multicast deployment, we introduce and analyze BIDIR-SAM, the rst structured overlay multicast scheme based on bi-directional shared pre x trees. BIDIRSAM admits predictable costs growing logarithmically with increasing group size. We also present a broadcast approach for DHT-enabled P2P networks. Both schemes are integrated in a standard compliant hybrid group communication architecture, bridging the gap between overlay and underlay as well as between interand intra-domain multicast.

Scalable IP Multicast Sender Access Control for Bi-directional Trees

Bi-directional shared tree is an efficient routing scheme for interactive multicast applications with multiple sources. Given the open-group IP multicast service model, it is important to perform sender access control so as to prevent group members from receiving irrelevant data, and also protect the multicast tree from various Denial-of-Service (DoS) attacks. Compared with source specific tree...

Scalable sender access control for bi-directional multicast routing

Bi-directional shared tree is an efficient routing scheme for interactive multicast applications with multiple sources. Given the open-group IP multicast service model, it is important to support sender access control in order to prevent group members from receiving irrelevant data, and also to protect the multicast tree from Denial-of-Service (DoS) attacks. Compared with source specific and un...

Towards dynamic sender access control for bi-directional multicast trees

Bi-directional shared tree is an efficient routing scheme for many-to-many multicast applications (e.g. multiparty videoconferencing, interactive distance lecturing and Internet games etc). Given the open-group IP multicast service model, it is important to perform sender access control so as to prevent group members from receiving irrelevant data, and also protect the multicast tree from vario...

S Calable and Robust Location Aware Multicast Algorithm ( Srlama ) for Manet

An ad hoc network is composed of mobile nodes without the intervention of any fixed infrastructure or central administration. Multicasting is intended for group-oriented communication. A lot many applications depend on one-to-many or many-to-many dissemination of the information. However, in ad hoc environment, multicasting protocols are faced with the challenge of producing multihop routes und...

Scalable Energy Efficient Location Aware Multicast Protocol for MANET (SEELAMP)

Multicast plays an important role in implementing the group communications in bandwidth scarce multihop mobile ad hoc networks. However, due to the dynamic topology of MANETs it is very difficult to build optimal multicast trees and maintaining group membership, making even more challenging to implement scalable and robust multicast in Mobile Ad hoc Networks (MANET). A scalable and energy effic...
