The formation of a Cognitive Personal Area Network (CPAN) involves a group of nodes connecting to a dedicated coordinator. In this paper, we propose a protocol for the formation of a CPAN in which nodes arrive randomly and their times to rendezvous (TTRs) with the CPAN coordinator may overlap, partially or fully, with one another. We develop an analytical model for the group joining time, i.e., the...
We present an anonymous authentication scheme for vehicular networks, that provides conditional anonymity to collocated vehicles. A modified ECDSA mechanism utilizes the position information of vehicles operating together in close proximity for generation and verification of elliptic curve-based signatures on safety and other application messages. This waives the requirement of a third party public-key...
