In this paper, we propose and analyze a multicast application called SOMA (SynchrOnous Multicast Application) which offers multicast file transfer service in an asymmetric intra-campus environment. For efficient bandwidth utilization, SOMA uses IP multicasting. We also propose a complete multicast transport protocol involving both, the flow and error correction algorithms. The protocol adapts t...

Secure multicast communication is a significant requirement in emerging applications in adhoc environments like military or public emergency network applications. Membership dynamism is a major challenge in providing complete security in such networks. This paper proposes a efficient Group Based Multicast Hierarchy (GBMH) algorithm for secret multicast communication, in which source nodes used ...

Mobile Ad-Hoc Network (MANET) is a dynamic, multi-hop and autonomous network composed of light wireless mobile nodes. Multicast has great importance in MANET due to their inherent broadcast capability. However, due to the dynamic topology of MANETs to build optimal multicast trees and maintaining group membership a lot many control messages required. These overhead consume the mobile node resou...

This paper discusses different approaches of providing multicast traffic for mobile hosts. Mobile IPv6 is used for mobility support. The network employs Protocol Independent Multicast Dense Mode (PIM–DM) for multicast routing and Multicast Listener Discovery (MLD) to collect multicast group membership information. We identify and analyze interoperation problems concerning membership control for...

This paper describes a framework of QoS management for one-to-many multicast communications in the context of a new multicast transport protocol called the Enhanced Communication Transport Protocol (ECTP). ECTP is a transport protocol designed to support Internet multicast applications, such as audio and video, which is currently being standardised in ITU.T SG7. ECTP operates over IP networks t...

A novel efficiency and effectiveness Internet multicast routing protocol is presented with short delay, high throughput, resource utilization and scalability for a single multicast group g. The protocol has two features: (1) Multiple Shared-Trees (MST) are configured to provide efficient, dynamic and quality multicast routing; (2) Anycasting approach is used to form the tree roots into an anyca...

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 ...

Multicast Extensions to OSPF Status of this Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the " Internet Official Protocol Standards " (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract T...

This paper presents the performance analysis of topological multicast routing algorithms on mobile wireless ad-hoc networks. Flooding and OnDemand Multicast Routing Protocol (ODMRP) are simulated and compared with Topological Multicast Routing Protocol (ToMuRo) over a pedestrian scenario. The scenario evaluated considers one multicast transmitter and one, two, and three multicast receivers unde...

Multimedia applications, such as videoconferences, require an efficient management of the Quality of Service (QoS) and consist of a great number of participants which requires the use of multicast routing protocol. Unlike unicast protocol, multicast protocol handles a great number of users while minimizing both network overhead and bandwidth consumption. However, combining multicast routing and...
