Overlay networks are becoming a popular vehicle for deploying advanced services in the Internet. One such service is multicast. Unlike conventional IP multicast, which requires universal deployment of network layer mechanisms, the overlay multicast model leverages the existing unicast mechanism and offers many service flexibilities to applications. Implementing multicast without requiring netwo...

Multicast is an important collective communication operation on multicomputer systems, in which the same message is delivered from a source node to an arbitrary number of destination nodes. The star graph interconnection network has been recognized as an attractive alternative to the popular hypercube network. In our previous work on wormhole star graph networks routing, we proposed a path-base...

In this paper, we propose a novel fault-tolerant multicast algorithm for n-dimensional wormhole routed hypercubes. The multicast algorithm will remain functional if the number of faulty nodes in an n-dimensional hypercube is less than n. Multicast is the delivery of the same message from one source node to an arbitrary number of destination nodes. Recently, wormhole routing has become one of th...

Most of the multicast routing protocols for ad-hoc networks today are based on shared or source-based trees; however, keeping a routing tree connected for the purpose of data forwarding may lead to a substantial network overhead. A different approach to multicast routing consists of building a shared mesh for each multicast group. In multicast meshes, data packets can be accepted from any route...

Multicasting is intended for group-oriented communication services. One particularly challenging environment for multicast is a Mobile Ad-Hoc Network (MANET) where, the network topology can change randomly and rapidly, at unpredictable times. As a result, several specific multicast routing protocols for MANET have been proposed. Multicast approaches can generally be categories into two: proacti...

There are two major difficulties in real-time multicast connection setup. One is the design of an efficient distributed routing algorithm which optimizes the network cost of routing trees under the real-time constraints. The other is the integration of routing with admission control into one single phase of operations. This paper presents a real-time multicast connection setup mechanism, which ...

Network Coding is most promising aspect of WSN. This Network Coding method is combined with multipath routing protocol to form NCMR protocol.(network coding based multipath routing protocol).This protocol is used to obtain energy efficient wireless sensor network.. These protocol leads to decrease the number of constrain routes & the total time of transmission. This protocol is applied on unica...

Recently, we had proposed a novel network density and mobility aware energy-efficient broadcast route discovery strategy (called DMEF) to discover stable routes in mobile ad hoc networks (MANETs). DMEF works by letting each node to dynamically choose its own broadcast transmission range for the route discovery messages depending on the perceived number of neighbour nodes in its default maximum ...

This paper proposes a Delay-Based Multicast Routing Protocol (DBMRP) for multicast transmissions in ad hoc wireless networks. The DBMRP uses an on-demand, source-based multicast routing protocol, which is based on the tree forwarding methodology. The queuing delay and link delay of each visited mobile node are used to establish the multicast tree. In addition, DBMRP selects Displacement Nodes (...

This paper presents a novel multicast routing protocol for mobile ad hoc wireless networks. The protocol, termed ODMRP (On-Demand Multicast Routing Protocol), is a mesh-based, rather than a conventional treebased, multicast scheme and uses a forwarding group concept (only a subset of nodes forwards the multicast packets via scoped flooding). It applies on-demand procedures to dynamically build ...
