Adaptive Processing for Multi-user Stream Service over Web-Based Broadcasting Stream

Adaptive processing overlay multicasting for Web-based broadcasting provides efficient service for multi-users sharing application with single sources. A mechanism is proposed by locally applying children-parents-role swapping in trees by adopting a swapping function in overlay protocol. Performance efficient results for real-time, concurrent service is achieved with stream trees with locally swapped nodes having maximum peak RTTs of about 0.6 seconds - better than TBCP and HMTP. The proposed scheme does well in terms of session connections, especially when multi-userspsila number grows. Number of hosts against group size after the local swapping seems to be the best and maximum average relative delay penalty (ARDP) of less than 6 units indicates that the new mechanism welcomes modest services in stream groups with affordable penalty, regardless of hostspsila number. The swapped trees perform better in terms of costs, average RTT, number of hosts, and ARDP.
