Abstract

Dramatic recent improvements in the computing power, memory capacity, screen size, and video quality of mobile devices have resulted in substantial demand for mobile multimedia services. However, these improvements have also resulted in increased demands for limited and expensive wireless bandwidth and for the energy of mobile devices with limited battery capacities. In this talk, I will consider the problem of multicasting multiple video streams from a wireless base station to many mobile receivers over a common wireless channel. I will present a sequence of increasingly sophisticated approaches to the problem of optimizing both the bandwidth utilization of the wireless channel and the energy usage of the mobile receivers.
