Multiple multicast trees have been shown to increase the performance of data distribution when compared with single tree multicast. Node loss and congestion changes the performance characteristics of the multicast trees. Multicast tree performance feedback can be used to determine the optimal tree to use based on the feedback. We further examine an optimizing methodology, Probabilistic Multicas...

In this paper mobile multicast mechanism based on IEEE 802.21 MIH (Media Independent Handover) for efficient network resource usage is proposed. We support the efficiency of network resource usage and fast multicast handover. The proposed architecture adopts multicast manager concept to MIH framework in order to efficiently perform mobile multicast handover, and adds the new MIH messages dedica...

Multicast distribution in mobile wireless networks is a topic that has recently begun to be explored. For multicasting, conventional protocols deene a multicast group as a collection of hosts which register to a multicast group address. However, in this paper, we deene a location-based multicast group which is based on a speciic region (\Multicast Region") in a mobile ad hoc network (MANET). Ho...

In this paper, a multicast scheme for UMTS which only requires insignificant modifications in the current UMTS network infrastructure is analyzed. We analytically present the multicast routing mechanism behind our scheme as well as the multicast group management functionality of it. Furthermore, we present an evaluation of our scheme in terms of its performance. The critical parameters for the ...

In this paper, we present a novel approach, stealth multicast, which offers a practical solution for the adoption of network-level IP multicast. Rather than focusing on a global scale such as with previous approaches, stealth multicast optimizes efficiency on a domain-wise scale. In short, stealth multicast dynamically combines redundant data payloads into virtual groups for multicast transmiss...

Disruption Tolerant Networks (DTNs) technologies are emerging solutions to networks that experience frequent partitions. As a result, multicast design for DTNs is a considerably more difficult problem compared to that of Internet and mobile ad hoc networks. In this paper, we first investigate three basic DTN multicast strategies, including unicast-based multicast (U-Multicast), static-tree-base...

This paper proposes the ASIMcast (Any-Source Implicit Multicast) protocol which builds a bidirectional tree for routing of multicast traffic. ASIMcast includes features addressing issues which have been slowing down the deployment of multicast until now. ASIMcast does not use class D IP addresses to forward multicast data but normal unicast addresses instead. This prevents the collision of diff...

Despite the fact that global multicast is still not possible in today’s Internet, many local networks are already multicast-capable (the so-called multicast “islands”). However, most application-layer multicast (ALM) protocols for streaming have not taken advantage of the underlying IP multicast capability. As IP multicast is more efficient, it would be beneficial if ALM can take advantage of s...

This paper proposes DINloop (Data-In-Network loop) based multicast with GMPLS (generalized multiprotocol label switching) to overcome the scalability problems existing in current inter-domain multicast protocols. In our approach, multiple multicast sessions share a single DINloop instead of constructing individual multicast trees. DINloop is a special path formed using GMPLS to establish LSPs (...

In this report, we revisit a much explored topic in networking the search for a simple yet fully general and efficient multicast design. The many years of research into multicast routing have led to a generally pessimistic view that the complexity of multicast routing and interdomain multicast in particular can only be overcome by restricting the service model, as in the case of single-source m...
