Abstract— In this paper, collocated and distributed spacetime block codes (DSTBCs) which admit multi-group maximum likelihood (ML) decoding are studied. First the collocated case...
Abstract—In this paper, we propose a distributed key management framework based on group signature to provision privacy in vehicular ad hoc networks (VANETs). Distributed key man...
Abstract-- Due to the limited energy supplies of nodes in wireless networks, achieving energy efficiency is crucial for extending the lifetime of these networks. Thus, we study eff...
—Code dissemination in wireless sensor networks refers to the process of disseminating a new code image via wireless links to all sensor nodes after they are deployed. It is desi...
