multicasting videos
In computer networking, multicast is group communication[1] where data transmission is addressed to a group of destination computers simultaneously. Multicast can be one-to-many or many-to-many distribution.[2] 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

Massive MIMO Multicasting in Noncooperative Cellular Networks.

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

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

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

The number and variety of mobile multicast applications are growing at an unprecedented and unanticipated pace. Mobile network providers are in front of a dramatic increase in multicast traffic load, and this growth is forecasted to continue in fifth-generation (5G will need to be a paradigm shift that includes very high carrier frequencies with massive bandwidths, extreme base station and device densities and unprecedented numbers of antennas. But unlike the previous four generations, it will also be highly integrative: tying any new 5G air interface and spectrum together with LTE and WiFi to provide universal high-rate coverage and a seamless user experience. To support this, the core network will also have to reach unprecedented levels of flexibility and intelligence, spectrum regulation will need to be rethought and improved, and energy and cost efficiencies will become even more critical considerations. This paper discusses all of these topics, identifying key challenges for future research and preliminary 5G standardization activities, while providing a comprehensive overview of the current literature, The global bandwidth shortage facing wireless carriers has motivated the exploration of the underutilized millimeter wave (mm-wave) frequency spectrum for future broadband cellular communication networks. There is, however, little knowledge about cellular mm-wave )
