— 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...
Abstract—A cross-layer communication protocol called VSNModule is introduced for Wireless Video Sensor Networks based on UltraWideBand (UWB) radio technology at the physical laye...

Recent years have witnessed a growing interest in the application of wireless sensor networks in unattended environments. Nodes in such applications are equipped with limited ener...
Given a wireless network where each link undergoes small-scale (Rayleigh) fading, we consider the problem of routing a message from a source node to a target node while minimizing...
