—This paper deals with distributed beamforming techniques for wireless networks with half-duplex amplify-andforward relays. Existing schemes optimize the beamforming weights base...
Abstract— This paper discusses channel estimation in a cooperative orthogonal frequency-division multiplexing (OFDM) network in the presence of frequency offsets. Both the amplif...
—In this paper we present findings from our windowing BitTorrent simulations and show that by carefully optimizing other factors a reasonable level of performance can be achieved...

—The probability of a miss in the detection of a signal in an optical communications system through the turbulent atmosphere using intensity modulation is studied. The turbulence...
Abstract— An important issue for supporting multimedia applications in multiple heterogeneous networks, a typical pervasive computing environment, is how to optimize the rate all...

—Security toolbars are used to protect naive users against phishing attacks by displaying warnings on suspicious sites. Recently, web browsers have added built-in phishing filte...
—Point of presence (PoP) level Internet maps are promising for tasks such as reasoning about the Internet evolution in time or Internet delay estimation. We thus suggest an effi...
