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...

We show that there is a trade off among mobility, capacity, and delay in ad hoc networks. More specifically, we consider two schemes for mobility of nodes in ad hoc networks. We d...

Random beamforming, where each node selects a main beam direction without any coordination with other nodes, has been proposed as a simple technique to improve connectivity in wire...
