Multicast is the ability of a communication network to accept a single message from an application and to deliver copies of the message to multiple recipients at different location. With the development of Internet, Multicast is widely applied in all kinds of multimedia real-time application: distributed multimedia systems, collaborative computing, video-conferencing, distance education, etc. I...

This paper presents a performance analysis of topological and geographical multicast routing algorithms for mobile wireless ad hoc networks. Flooding and On-Demand Multicast Routing Protocol (ODMRP) are simulated and compared with two novels protocols proposed: Topological Multicast Routing Protocol (ToMuRo) and Geographical Multicast Routing Protocol (GeMuRo) in pedestrian and vehicular scenar...

The issues of adaptive multicast wormhole routing in 2D mesh multicomputers are studied. Three adaptive multicast wormhole routing strategies are proposed and evaluated. The methods include minimal partially-adaptive, minimal fully-adaptive, and nonminimal adaptive routing. All the algorithms, which are the rst deadlock-free adaptive multicast wormhole routing algorithms ever proposed, are show...

Mobile Ad hoc NETworks (MANETs), represent an emerging class of networks in which wireless mobile nodes operate independent of a backbone infrastructure. While hosts in traditional networks often rely on a designated router to forward data, every host in a MANET is required to route and forward data. The network hosts, such as laptops and personal digital assistants, operate on constrained batt...

The future Internet is expected to support multicast applications with quality of service (QoS) requirements. To facilitate this, QoS multicast routing protocols are pivotal in enabling new receivers to join a multicast group. However, current routing protocols are either too restrictive in their search for a feasible path between a new receiver and the multicast tree, or burden the network wit...

IP multicast technology is highly advantageous for various applications and future needs in the Internet. Yet, it is generally recognized that the IP multicast routing protocol is fairly complex and nonscalable and requires additional maintenance and operational cost to network administrators. Although there has been much research related to IP multicast and most router vendors already support ...

In network multimedia applications, such as multiparty teleconferencing, users often need to send the same information to several (but not necessarily all) other users. To manage such one-to-many or many-to-many communication e ciently in wide-area internetworks, it is imperative to support and perform multicast routing. Multicast routing sends a single copy of a message from a source to multip...

A mobile ad-hoc network (MANET) is composed of mobile nodes without any infrastructure. Mobile nodes self-organize to form a network over radio links. The goal of MANETs is to extend mobility into the realm of autonomous, mobile and wireless domains, where a set of nodes form the network routing infrastructure in an ad-hoc fashion. The majority of applications of MANETs are in areas where rapid...

This report presents routing algorithms for many-to-many multicast connections with band-width requirements. The objective is to compute a connectivity structure among multicast members of low cost, taking into account their bandwidth requirements. We rst study the complexity of routing multicast connections with bandwidth reservation. Based on derived impossibility results , we propose a clust...
