In this paper, an efficient Fibonacci series based hierarchical protocolHFTM (Hierarchical Fibonacci Tree Multicast) is proposed for applicationlayer multicast. It adopts the idea of layer and cluster to construct multicast group members into a hierarchical architecture. During the cluster formation, it considers the underlying network properties to reduce packet delivering on costly links. In ...

Most currently proposed solutions to application-level multicast organize the group members into an application-level mesh over which a Distance-Vector routing protocol, or a similar algorithm, is used to construct source-rooted distribution trees. The use of a global routing protocol limits the scalability of these systems. Other proposed solutions that scale to larger numbers of receivers do ...

Mobile ad hoc networks are becoming an important concept of modern communication technologies and services. It provides some advantages to this communication world such as self-organizing and decentralization. In this paper, we are going to design a cluster-based multi source multicast routing protocol with new cluster head election, path construction and maintenance techniques. The main object...

We describe a protocol to construct optical multicast trees in lambdaswitched networks running PIM-SM. Based on the MPLS architecture, the protocol maps a multicast tree constructed by PIM-SM onto point-to-multipoint LSPs that are connected to form an equivalent WDM multicast tree. LSP set-up request is receiver-initiated in the protocol. A mechanism to collect information about the capability ...

QOSPF [6-8] is a well-known link state based unicast QoS routing protocol. It is a precomputation-based approach with the strength of low routing latency but suffers from high control and storage overheads. Its overhead will be exacerbated not only for large-scale network but also for the extension to support multicast routing. Thus, few researches strive to directly extend the work of QOSPF to...

In wireless networks current standard MAC layer protocols don’t provide any error correction scheme for broadcast/multicast. In this paper, we enhance a Leader Based Protocol (LBP) and propose a Beacon-driven Leader Based Protocol (BLBP) for the MAC layer multicast error control. To guarantee a very low Packet Loss Ratio (PLR) under strict delay constraints for video multicast over a Gilbert-El...

Development of new multicast monitoring techniques and tools has not met demand. Most of the existing tools have only marginal utility in today's multicast infrastructure. This is the case because these tools lack the ability to handle the latest routing protocols or because they rely on application layer data like the Realtime Transport Protocol (RTP). Our goal is to develop a system that moni...

This document specifies Version 3 of the Internet Group Management Protocol, IGMPv3. IGMP is the protocol used by IP systems to report their IP multicast group memberships to neighboring multicast routers. Version 3 of IGMP adds support for ’’source filtering’’, that is, the ability for a system to report interest in receiving packets *only* from specific source addresses, or from *all but* spe...

Routing protocol in wireless sensor network (WSN) has always been a frequently adopted topic of research in WSN owing to many unsolved issues in it. This paper discusses about the multicast routing protocols in WSN and briefs up different forms of standard research contribution as well as significant recent research techniques toward leveraging the performance of multicast routing. The paper th...

This study presents a forwarding nodes selection scheme for zone-based multicast routing protocols to reduce transmission routing control overhead. The feasibility of the proposed scheme is demonstrated over mobile ad hoc networks (MANETs), and compared with the multicast zone routing protocol (MZR) in terms of the routing control overhead and packet delivery ratio. In this work, the proposed s...
