Multicast scheduling for stereoscopic video in wireless networks

Multimedia Tools and Applications, 2015
Stereoscopic video multicast over wireless network is a challenging issue due to large bandwidth requirement, limited resource, and heterogeneous user channel conditions. Recently, most existing methods for stereoscopic video multicast employ symmetric video coding that transmits the same video quality for stereo views.

A New Multicast Scheduling Scheme for Cellular Networks

IEEE Wireless Communications Letters, 2014
In this paper, adaptive user selection for opportunistic multicast scheduling (A-OMS) is proposed to improve cellular network throughput. Unlike previous solutions, the number of users selected in each transmission time interval (TTI) is not considered to be a constant.

Geographic multicast routing based sleep scheduling

2017 International Symposium on Networks, Computers and Communications (ISNCC), 2017
Wireless Sensor Networks suffer from the limited bandwidth and power resources such as: energy, memory, CPU. Geographic multicast routing is appropriate for this kind of networks since it avoids the flooding request packets to all nodes to find destinations, which consumes a lot of energy and bandwidth.

Cognitive Multicast Pilot Scheduling for Heterogeneous Networks

2010 IEEE 72nd Vehicular Technology Conference - Fall, 2010
With the increasing convergence and cooperation among wireless networks, network awareness of user equipment (UE) has become very important. A practical solution for network information delivery for UE, Cognitive Pilot Channel (CPC), has recently been proposed.

Scheduled multicast overlay for bandwidth-intensive applications

2012 16th International Conference on Optical Network Design and Modelling (ONDM), 2012
In this paper we investigate the multicast advance reservation problem in wavelength division multiplexed (WDM) optical networks. Under the advance reservation traffic model (also know as scheduled traffic), connection requests specify their start time to be some time in the future and also specify their holding times.

Multicast scheduling for switches with multiple input-queues

Proceedings 10th Symposium on High Performance Interconnects, 2003
We address the problem of serving multicast traffic in input-queued packet switches. Head-of-line blocking is a major problem in input-queued switches. It can be avoided in unicast switches by maintaining a queue per output port at each input port.

Wireless Multicast Scheduling With Switched Beamforming Antennas

IEEE/ACM Transactions on Networking, 2012
Using beamforming antennas to improve wireless multicast transmissions has received considerable attention recently. A recent work proposes to partition all single-lobe beams into groups and to form composite multilobe beam patterns to transmit multicast traffic.

Optimal beam scheduling for multicasting in wireless networks

Proceedings of the 15th annual international conference on Mobile computing and networking, 2009
We consider the problem of efficient link-layer multicasting in wireless networks with switched beamforming antennas. The inherent tradeoff between multicasting and beamforming -- the broadcast advantage of low-gain omni-directional transmissions versus the high-gain but spatially restricted transmissions of beamforming antennas -- makes this problem ...

Optimization of delay performance in multicast CPC scheduling

2013 IEEE Wireless Communications and Networking Conference (WCNC), 2013
Recently, cognitive pilot channel (CPC) has been proposed to assist spectrum awareness and network selection in the heterogeneous network and dynamic spectrum access mechanism. The CPC channel can provide the necessary wireless environment information for the terminals and avoid long time- and energy-consumption for spectrum scanning.

A Downlink Scheduler for Multicasting Wireless Video-on-Demand

IEEE Transactions on Mobile Computing, 2016
We consider a video delivery problem in which a server multicasts a video to several users over a wireless broadcast channel. Users arrive and depart asynchronously, and when a user arrives, he/she wishes to watch the video from the beginning. Existing approaches for this problem assume that the server is either completely aware of the state of the ...
