Optimal beam scheduling for multicasting in wireless networks
Karthikeyan Sundaresan, Kishore Ramachandran, Sampath Rangarajan · 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 especially challenging.
