Secure Location Verification for Vehicular Ad-Hoc Networks
In this paper, we examine one of the security issues in vehicular ad-hoc network (VANETs): position-spoofing attack. We propose a novel Secure Location Verification (SLV) scheme to...

On the Capacity of One-Sided Two User Gaussian Fading Broadcast Channels
In this paper, we investigate upper and lower bounds on the capacity of two-user fading broadcast channels where one of the users has a constant (non-fading) channel. We use the Co...

Alternating Cooperative Transmission for Energy-Efficient Broadcasting
We propose a broadcast protocol that is based on a form of cooperative diversity called the Opportunistic Large Array (OLA). In the initial broadcast, an SNR ("transmission&qu...
