Bridging the Gap between Response Time and Energy-Efficiency in Broadcast Schedule Design [chapter]

Wai Gen Yee, Shamkant B. Navathe, Edward Omiecinski, Christopher Jermaine
2002 Lecture Notes in Computer Science  
In this paper, we propose techniques for scheduling data broadcasts that are favorable in terms of both response and tuning time.  ...  By generating broadcast schedules based on Acharya et al.'s broadcast disk paradigm, we bridge the gap between these two mutually exclusive bodies of work-response time and energy expenditure.  ...  Acknowledgements The authors would like to thank Professors Mostafa Ammar and Krithi Ramamritham for their technical comments and Mireille Jacobson for her editorial advice.  ...
