In computer networking, multicast is group communication where data transmission is addressed to a group of destination computers simultaneously. Multicast can be one-to-many or many-to-many distribution. Multicast should not be confused with physical layer point-to-multipoint communication.
A source-based algorithm for delay-constrained minimum-cost multicasting

ABSTRACT A new heuristic algorithm is presented for constructing minimum-cost multicast trees with delay constraints. The new algorithm can set variable delay bounds on destinations and handles two variants of the network cost optimization goal: one minimizing

Application-layer multicasting with delaunay triangulation overlays
free download

Application-layer multicast supports group appli-cations without the need for a network-layer multicast protocol. Here, applications arrange themselves in a logical overlay network and transfer data within the overlay. In this paper, we present an application-layer multicast

Massive MIMO Multicasting in Noncooperative Cellular Networks.
free download

We study physical layer multicasting in cellular networks where each base station (BS) is equipped with a very large number of antennas and transmits a common message using a single beamformer to multiple mobile users. The messages sent by different BSs are

Two distributed algorithms for multicasting multimedia information

This paper addresses the problem of e ective multicast tree construction for interactive audiovisual communication to several destinations. We believe that the e ectiveness of a multicast tree for such applications is determined by two factors:(i) the end-to-end delay

Evaluation of Multicasting Algorithms in Manets.

Disaster relief, education, and military are common situations where mobile nodes need to communicate in areas without any preexisting infrastructure. In these situations, MANETs (Mobile Ad-Hoc Networks) are used. When these nodes need one-to-many or many-to-many

40-Gb/s optical switching and wavelength multicasting in a two-pump parametric device
free download

A two-pump parametric architecture is used to demonstrate all-optical packet and bit-level switching at OC-768 data rates. We show that a switched signal can be simultaneously replicated in four parametric bands with arbitrary conjugate states. The conversion

Multicasting mesh AER: a scalable assembly approach for reconfigurable neuromorphic structured AER systems. Application to ConvNets
free download

This paper presents a modular, scalable approach to assembling hierarchically structured neuromorphic Address Event Representation (AER) systems. The method consists of arranging modules in a 2D mesh, each communicating bidirectionally with all four

Multicasting in ad hoc networks
free download

An ad hoc network is a dynamic wireless network with the engagement of cooperative nodes without a fixed infrastructure. Multicasting is intended for group communication that supports the dissemination of information from a sender to all the receivers in a group. Problems in ad

Reliable multicasting in MANETs
free download

Multicasting is the transmission of datagrams (packets) to a group of zero or more hosts identified by a single destination address. Maintaining group membership information and building an optimal multicast distribution structure (typically in the form of a routing tree) is

Multicasting in Delay Tolerant Networks: Delegation Forwarding.
free download

Delay tolerant networks (DTNs) are a kind of wireless mobile network which may lack continuous network connectivity. Multicast supports the distribution of data to a group of users, a service needed for many potential DTNs applications. While multicasting in the

MZRP: an extension of the zone routing protocol for multicasting in MANETs
free download

In recent years, a variety of unicast and multicast routing protocols for Mobile Ad hoc wireless NETworks (MANETs) have been developed. The Zone Routing Protocol (ZRP) is a hybrid unicast protocol that proactively maintains routing information for a local

New technologies of multicasting in MANET

Multicasting can efficiently support a variety of applications that are characterized by the close degree of collaboration typical of many ad hoc applications currently envisioned. Within the wired network, well-established routing protocols exist to offer efficient

Link failure recovery for mpls networks with multicasting
free download

Link failures are a common cause of service disruption in computer networks. When a link of a network fails, all communications which were using the failed link are temporarily interrupted. Techniques have been engineered to alleviate the consequences of hardware
