Power management is one of the vital issue in wireless sensor networks, where the lifetime of the network relies on battery powered nodes. Transmitting at high power reduces the l...
— We consider the fundamental delay tradeoffs for minimizing energy expenditure in a multi-user wireless downlink with randomly varying channels. First, we extend the BerryGallag...
— Energy efficiency is widely understood to be one of the dominant considerations for Wireless Sensor Networks. Based on historical data and technology trends, the receiver ener...
—In this paper, we investigate the transmission-power assignment problem for k-connected mobile ad hoc networks (MANETs), the problem of optimizing the lifetime of a MANET at a g...

Abstract-- We investigate cascade dynamics in thresholdcontrolled (multiplex) propagation on random geometric networks. We find that such local dynamics can serve as an efficient, ...
