Performance Analysis of a Dynamic Compact Multicast Routing Scheme

چکیده
Les algorithmes de routage compact ont pour objectif de trouver le meilleur compromis entre le nombre de bit mémoire nécessaire pour stocker les entrées des tables de routage et le coût des chemins de routage que ces algorithmes produisent. Dans cet article, nous présentons un algorithme de routage compact permettant la construction dynamique de chemins de routage point-à-multipoint pour la distribution de données depuis une source quelconque vers un ensemble quelconque de destinations. L'arbre déterminé par ce chemin et servant à la distribution du trafic est communément appelé arbre de distribution de trafic multicast. Au moyen de cet algorithme, cet arbre est capable d'évoluer dynamiquement en fonction de l'arrivée des demandes de souscription à la source de trafic associée. Nous étudions les compromis entre l'étirement produit par l'algorithme de routage, la taille et le nombre d'entrées résultantes dans les tables de routage ainsi que le coût de la communication.

Design and Performance Analysis of Dynamic Compact Multicast Routing
Recently introduced by Abraham et. al, compact multicast routing algorithms construct point-to-multipoint routing paths from any source to any set of destinations. The present paper introduces a different approach by proposing a name-independent compact multicast routing algorithm that is leaf-initiated, fully distributed, and independent from the underlying unicast routing. By means of the pro...
متن کاملIterative Research Method Applied to the Design and Evaluation of a Dynamic Multicast Routing Scheme
Following the iterative research cycle process, this chapter elaborates a methodology and documents the steps followed for the design of a dynamic multicast routing algorithm, referred to as Greedy Compact Multicast Routing. Starting from the design of the dynamic multicast routing algorithm, we then evaluateby simulation on large-scale topologies its performance and compare them with the Abrah...
متن کاملInterference-Aware and Cluster Based Multicast Routing in Multi-Radio Multi-Channel Wireless Mesh Networks
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...
متن کاملCompact Multicast Routing
In a distributed network, a compact multicast scheme is a routing scheme that allows any source to send messages to any set of targets. We study the trade-off between the space used to store the routing table on each node and the stretch factor of the multicast scheme – the maximum ratio over all sets of nodes between the cost of the multicast route induced by the scheme and the cost of a stein...
متن کاملMulticast Routing in Wireless Sensor Networks: A Distributed Reinforcement Learning Approach
Wireless Sensor Networks (WSNs) are consist of independent distributed sensors with storing, processing, sensing and communication capabilities to monitor physical or environmental conditions. There are number of challenges in WSNs because of limitation of battery power, communications, computation and storage space. In the recent years, computational intelligence approaches such as evolutionar...
