Equitable Optimization for Multicast Communication

International Journal of Decision Support System Technology, 2020
Multicast communication is characterized by the multiplicity of streams defining different groups, where each stream has multiple sources. A multicast communication tends to flood the network with a large number of flows that can overload some nodes and unload others. This imbalance in the load distribution weakens network performance and could produce

Multicast communication on the Unison network

Computer Communications, 1990
Abstract A multicast access architecture for a multiservice network is described. The system is based on the use of a distributed set of multicast agents which are responsible for regulating access to the service and for effecting the distribution of data.

Performance of multicast communication on hypercubes

Journal of Computer Science and Technology, 1993
Based upon hypercube multiprocessor systems, this paper analyses in detail the communication performance under the background of the greedy multicast algorithm GMA. The mean delay time of a message both at a node and in the system under multicasting is derived.

System utility based resource allocation for D2D multicast communication in software-defined cellular networks

AEU - International Journal of Electronics and Communications, 2018
Device-to-device (D2D) multicast communication is a useful way to improve the communication efficiency of local services. This study considers a scenario of D2D multicast communication in software defined cellular network and investigates the frequency ...

Group Communication and Multicast

2001
In this paper we propose a group communication architecture for the Internet. This architecture is implemented as a middleware which provides a separation between a general group communication service model, and the multicast mechanisms used to implement this service.

Energy-Efficient RSMA for Multigroup Multicast and Multibeam Satellite Communications

IEEE Wireless Communications Letters, 2023
This letter studies energy-efficient rate-splitting multiple access (RSMA) for multigroup multicast and multibeam satellite communication systems. Specifically, we minimize the unmet system capacity, which means the rate difference between the requested ...

Secure Multicast Communications via RIS Against Eavesdropping and Jamming With Imperfect CSI

IEEE Transactions on Vehicular Technology, 2023
Eavesdropping and jamming pose great threats to the security of wireless communication. In this paper, a secure multicast communication system of transmitting different messages to a group of users based on reconfigurable intelligent surfaces (RIS) is ...

Dimensioning multicast‐enabled communications networks

Networks, 2002
AbstractThis paper concerns the network design problem of dimensioning capacity, available in discrete, nonuniform levels, for multicast traffic in a backbone communications network. An integer programming model, which includes embedded models for the Steiner tree problem in graphs, is proposed.

Multicast support for group communications

Computer Networks and ISDN Systems, 1991
Abstract This paper describes a multicast model which can be integrated into existing unicast communication systems to provide better support for group communications. Multicast services are becoming more important, as more and more of today's network workstation environments are used to provide group communications for the exchange of multimedia ...
