Channel assignment schemes in Multi-Radio Wireless Mesh Networks (MR-WMNs) usually leave several links sharing the same channel within overlapped transmissions or interference ranges; this is especially true when only one radio is used or when the number of radios is very small compared to the number of orthogonal channels. In order to further improve MR-WMN performance, especially for mobile multimedia...
Multicast routing with quality-of-service constraints is one of the most important problems in computer networks as constrained Steiner tree problem. It is a well-known NP-complete problem, which has various real-time multimedia applications in high-speed networks. In this paper, we propose algorithms to solve the bandwidth-delay-constrained least-cost multicast routing problem based on Tabu search...
The real time communication networks are designed to support multimedia applications requiring quality of services (QoS). The multicasting is needed when number of users want to communicate simultaneously. This paper present an approach based on evolutionary programming to solve the QoS constrained multicast routing problem, which is a NP complete problem. The multicast tree is obtained corresponding...
Packet classification enables network routers to provide advanced network services including network security, quality of service (QoS) routing, and multimedia communications. In order to classify a packet, network nodes must perform a search over a set of filters using multiple fields of the packet as the search key. Viewing the classification problem geometrically, classifying an arriving packet...
High speed modern communication networks are required to integrate and support multimedia application which requires differentiated quality-of-service (QoS) guarantees. Routing mechanism is a key to success of future communication networking. However, it is often complicated by the notion of guaranteed QoS, which can either be related to time, cost, packet loss or bandwidth requirements. Communication...
Multimedia applications are becoming more and more popular on today's Internet. Given the enormous development costs and less flexibility, traditional monolithic based approaches are not suitable for building large-scale multimedia systems. By composing of distributed, autonomous services dynamically to provide more complex tasks, service composition provides an attractive way for building large-scale...
