Outage Constrained Robust Multigroup Multicast Beamforming for Multi-Beam Satellite Communication Systems

IEEE Wireless Communications Letters, 2019
We investigate outage constrained robust multigroup multicast beamforming for multi-beam satellite communication systems with full frequency reuse. Based on a satellite downlink beam domain channel model with channel phase uncertainty taken into account,

Scalable reliable multicast using multiple multicast groups

Proceedings of the 1997 ACM SIGMETRICS international conference on Measurement and modeling of computer systems, 1997
We examine an approach for providing reliable, scalable multicast communication, using multiple multicast groups for reducing receiver processing costs in a multicast session. In this approach a single multicast group is used for the original transmission of packets.

Multicast

2002
The advancement in optical fiber and switching technologies has resulted in new generation high-speed networks that can achieve speeds of up to a few gigabits per second. Also, the progress in audio, video and data storage technologies has given rise to new distributed real-time applications. These applications may involve multimedia, which require low

Scalable reliable multicast using multiple multicast channels

IEEE/ACM Transactions on Networking, 2000
We examine an approach for providing reliable, scalable multicast communication, involving the use of multiple multicast channels for reducing receiver processing costs and reducing network bandwidth consumption in a multicast session. In this approach a single multicast channel is used for the original transmission of packets.

Handling Multicast Video over Non Multicast Networks

2011 15th Panhellenic Conference on Informatics, 2011
In this paper we evaluate the basic methods of video transmission, focusing on multicast, the popularity of which has increased over the last years. Although the specific technique is able of reducing significantly the consumption of network resources, such as the bandwidth, the specifications of IEEE 802.11 family networks do not support the ...

Multicasting

Television & New Media, 2013
Paying particular attention to the ways in which lesbian consumers and programming are co-constituted, this article examines lesbian programming on cable TV as a strategic method for attracting audiences and branding networks. Drawing on interviews with TV industry practitioners and market researchers, I examine the impact of institutional beliefs and

Opportunistic Multicast Scheduling with Multiple Multicast Groups

2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011
The use of opportunistic multicast scheduling (OMS) for systems with multiple multicast groups is examined in this work. Here, a general downlink scenario where a single basestation is to transmit independent data streams to multiple groups of users is considered.

Aggregated Multicast for Scalable QoS Multicast Provisioning

2001
IP multicast suffers from scalability problem with the number of concurrently active multicast groups, while scalability of QoS multicast is even further from being solved. In this paper, we propose an approach to reduce multicast forwarding state and provision multicast with QoS guarantees. In our approach, multiple groups are forced to share a single

Island multicast : the combination of IP-multicast with application-level multicast

2014
With the availability and penetration of multicast-capable routers, many local networks in today's Internet are multicast-capable. However, achieving global IP multicast is still hindered by many management and technical difficulties. This is because routers interconnecting these local multicast-capable networks, or so-called "islands," are often ...

Probabilistic multicast: generalizing the multicast paradigm to improve scalability

Proceedings of INFOCOM '94 Conference on Computer Communications, 2002
The article considers the multicast-to-some generalization of the traditional multicast paradigm. In this form of communication, a multicast group is still associated with each multicast message. It is, however, only necessary for any randomly determined subset of the multicast group to receive a multicast message.
