Due to the massive popularity and spread of internet and advent of many new multimedia applications like Video Conferencing etc, the issue of multicast routing with multiple quality of service (QoS) constraints becomes more important. For Example, in order to ensure smooth playback of multimedia data, a video conference require guarantee on both end to end delay and loss probability. Artificial Immune...
Traffic engineering, particularly routing optimization, is one of the most important aspects to take into account when providing QoS in next generation networks (NGN). The problem of weight setting with conventional link state routing protocols for routing optimization has been object of study by a few authors. To solve this problem for big networks artificial intelligence heuristics have been used,...
Based on QoS constraints such as delay, delay jitter, bandwidth and packet loss metrics this paper describes a network model suitable for investigating the routing problem and presents a multicast routing algorithm with multiple QoS constraints based on GA and TS hybrid strategy. This algorithm takes advantage of GA and TS and overcomes the shortcomings of GA used in solving the multicast routing...
Multimedia communications and, in particular, multicast communications are widely used to distribute multimedia contents. When a certain quality of service (QoS) level must be guaranteed in the multicast tree construction then a Steiner tree problem is obtained, therefore a NP-complete problem must be faced. QoS multicast has a great relevance in the research community because it can offer high performances...
