Emerging optical networks have hierarchical architectures with varying capabilities at different levels. Moreover, many applications nowadays require multicast (one-to-many) connections. We propose a network model that has such a hierarchical architecture which is designed for multicast connections. We develop a multi-stage routing scheme which solves the routing problem in different levels of ...

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 ...

tolerant networks are a class of emerging networks that experience frequent and long-duration partitions. These networks have a variety of applications in situations such as crisis environments and deep-space communication. In this paper, we study the problem of multicasting in TNs. Multicast supports the distribution of data to a group of users, a service needed for many potential TN applicati...

In 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 bui...

Many new Internet applications require data transmission from a sender to multiple receivers. Unfortunately, the IP Multicast technology used today suffers from scalability problems, especially when used for small and sparse groups. Multicast for Small Conferences aims at providing more efficient support for example to audio conferences. In this work, we present a performance study of the conce...

In this paper we propose a multicast routing protocol for mobile ad hoc networks (MANETs). The protocol—termed Differential Destination Multicast (DDM)—differs from common approaches proposed for MANET multicast routing in two ways. Firstly, instead of distributing membership control throughout the network, DDM concentrates this authority at the data sources (i.e. senders) thereby giving source...

This paper addresses the problem of multicast (i.e., point to multipoint) routing in ATM networks. In particular, formal experimental methods are used to evaluate the relative performance of three simple multicast routing algorithms on simple mesh-based networks, using call-level simulation. The performance study focuses on the scalability of multicast routing algorithms with respect to network...

Anonymity is still a challenging issue in mobile ad hoc networks. Specially although operating as groups is required by many of ad hoc applications, there is only a little work on anonymous multicast routing algorithms. In this work we propose an Anonymous Multicast routing protocol for ad hoc networks called AnoMul based on the underlying unicast routing protocol ANODR proposed by J. Kong et a...

—Channel assignment assigns proper channels for interfaces, which helps dramatically reduce interference and improve network capacity. Routing selects proper paths for packet delivery, which can also help improve network capacity. In order to reduce computational complexity of joint multicast routing and channel assignment, multicast routing and channel assignment are regarded as two separate ...

This paper introduces AMRIS, a new multicast routing protocol for ad hoc wireless networks. AMRIS (Ad hoc Multicast Routing protocol utilizing Increasing id-numberS) is designed to operate independently of underlying unicast
