Time delay as well as error accumulation makes transmission of high-quality streaming media over multi-hop wireless networks more challenging. Since conventional TCP/IP-based protocol drops and retransmits the whole packet once error(s) occur above Physical Layer, which leads to long time delay and low efficiency in transmission, a new protocol for real-time streaming media transmission is proposed...
Distributed Virtual Environments like online games or 3D virtual worlds have become very popular in the last few years and a more substantial surge in popularity and use is expected. Because of the huge number of users, such environments will undergo a change of infrastructure from a centralized to a decentralized one, making higher demands on consistency issues. This paper addresses consistency problems...
Broadcasting is a common operation in on-demand multicast routing protocol to establish and refresh routing table. A straightforward broadcasting by flooding is usually very costly and will result in serious redundancy and contention. A conditioned broadcasting algorithm for on-demand multicast routing protocol is proposed, which computes the rebroadcast probability of packets through neighbor node...
The Application level multicast is an important technique for indirect communication model. However, there are few works to integrate them together. An Infrastructure for Application Level Multicast Routing in Publish/Subscribe system (IALMRS) is proposed in this paper. We realize a multicast routing protocol for such Publish/Subscribe systems based on IALMRS. From the tests for this multicast routing...
