We study the energy consumption of individual links in wireless sensor networks (WSN). Three widely used digital modulation schemes, i.e. MQAM, MPSK, and MFSK, are analyzed and com...
Abstract-- We identify an analytical expression for the distortion of a scalable video bitstream containing a Base Layer (BL) and one or more Enhancement Layer (EL) bitstreams. Con...
Information theoretic Broadcast Channels (BC) and Multiple Access Channels (MAC) enable a single node to transmit data simultaneously to multiple nodes, and multiple nodes to trans...

In this paper, we study the problems of resource and performance management in channelized wireless networks. For identifying research issues systematically, we propose a research...
—This paper deals with distributed beamforming techniques for wireless networks with half-duplex amplify-andforward relays. Existing schemes optimize the beamforming weights base...
