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 investigate the performance of priority-based access in a channel-hopping cognitive network, in particular the interaction between the number of packets each node is allowed to send in a single transmission cycle and the penalty coefficient that determines the amount of sensing to be done upon a successful transmission. Our results indicate that giving higher bandwidth allocation to low priority...
