Optimal power allocation in server farms [PDF]
Proceedings of the eleventh international joint conference on Measurement and modeling of computer systems, 2009 Server farms today consume more than 1.5% of the total electricity in the U.S. at a cost of nearly $4.5 billion. Given the rising cost of energy, many industries are now seeking solutions for how to best make use of their available power. An important question which arises in this context is how to distribute available power among servers in a server ...

Optimal Power Allocation over Multiple Identical Gilbert-Elliott Channels
, 2013 We study the fundamental problem of power allocation over multiple Gilbert-Elliott communication channels. In a communication system with time varying channel qualities, it is important to allocate the limited transmission power to channels that will be ...

The Power of Filling in Balanced Allocations
SIAM Journal on Discrete MathematicsWe introduce a new class of balanced allocation processes which are primarily characterized by "filling" underloaded bins. A prototypical example is the Packing process: At each round we only take one bin sample, if the load is below the average load, then we place as many balls until the average load is reached; otherwise, we place only one ball.

EURASIP Journal on Wireless Communications and Networking, 2009 The power allocation problem for multiuser wireless networks is considered under the assumption of amplify-and-forward cooperative diversity. Specifically, optimal centralized and distributed power allocation strategies with and without minimum rate ...

Journal of King Saud University: Computer and Information SciencesCurrently, most existing research on non-orthogonal multiple access (NOMA) systems converts power allocation into two independent procedures, i.e., inter-subchannel power allocation and intra-subchannel power allocation.

5G green cellular networks considering power allocation schemes
, 2015 It is important to assess the effect of transmit power allocation schemes on the energy consumption on random cellular networks. The energy efficiency of 5G green cellular networks with average and water-filling power allocation schemes is studied in ...
