DESCRIPTION:Power optimization on a random wireless network: A statistical 
 physics approach\nAris Moustakas (National and Capodistrian University of 
 Athens\, Dept of Physics)\nThe efficient use of transmitted power is impor
 tant in modern day wireless networks. Not only is the battery life of tran
 smitting devices thus extended\, but also the interference caused to neigh
 boring transmitters is minimized. There are iterative methods to obtain th
 e optimal power per node in a network\, however it is known that depending
  on the strength of the interference\, the problem may be infeasible. Howe
 ver\, the properties of the optimal power vector in a random network\, as 
 well as the convergence to it are not well understood. In this work we stu
 dy power optimization in a simple network with randomness. We show that th
 e problem can be mapped to an Anderson model and we analyze its properties
 \, such as the average power per transmitter\, its probability of failure\
 , the tails of its power distribution and dynamics using ideas from the th
 eory of disordered metals.\ncafé/thé seront servis à  14h00
