Multicast routing is one of the most important services in Multi Radio Multi Channel (MRMC) Wireless Mesh Networks (WMN). Multicast routing performance in WMNs could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. In this paper we want to address the multicast routing problem for a given channel assignment in WMNs. The channels...

In a networking environment, Quality-of-Service (QoS) routing plays an important role in the provision of real-time services with guaranteed throughput and bounded end-to-end delay. Its task is to nd a routing path which has su cient resources to support the requirements imposed by the applications. We propose several distributed algorithms for bandwidth-constrained routing and delay-constraine...

This paper proposes a novel traffic engineering framework able to automatically provide near-optimal OSPF routing configurations for QoS constrained scenarios. Within this purpose, this work defines a mathematical model able to measure the QoS compliance in a class-based networking domain. Based on such model, the NP-hard optimization problem of OSPF weight setting is faced resorting to Evoluti...

using new approaches to optimize the process of power transmission line routing can solve many complex problems which power transmission line routing decision-makers are faced. due to the expansion of involved parameters we can consider multi-objective evolutionary algorithms as appropriate method in this area. in this thesis with using multi-objective evolutionary algorithms nsga-ii and offere...

IP Multicast has been proposed in order to manage group communications over the Internet in a bandwidth efficient manner. Although such a proposition has been well studied, there are still some inherent problems ...

Unlike traditional routing schemes that route all traffic along the same path, multipath routing method split the traffic among several paths in order to ease congestion. It has been recognized by many that multipath routing can be fundamentally more efficient than the traditional approach of routing along single paths. Yet, in contrast to the single path routing approach, many research in the ...

Delay-constrained routing protocols are used to find paths subject to a delay constraint while efficiently using network resources. Many of the delay-constrained routing protocols that have been proposed in the literature give priority to cost minimization during the path computing process. With this approach, paths with end-to-end delays too close to the delay constraint are obtained. We belie...

Support for real time multimedia applications such as, video telephony, financial stock quote services, and multiplayer interactive games etc., is very essential in Mobile Ad hoc Networks (MANETs). Such applications require multiple Quality of Service (QoS) parameters to be satisfied, like bandwidth, end-toend delay, packet loss rate, jitter, etc. This paper considers the problem of finding nod...

The optimal solution of the multi-constrained QoS multicast routing problem is a tree-like hierarchical structure in the topology graph. This multicast route contains a feasible path from the source node to each of the destinations with respect to a set of QoS constraints while minimizing a cost function. Often, it is a tree. In other cases, the hierarchies can return several times to nodes and...
