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...
Efficient operation of a cognitive personal area network (CPAN) may be achieved if each data transmission is taxed by requiring the transmitting node to participate in cooperative sensing for a prescribed time period. We investigate the data transmission performance of this approach, as well as its sensing accuracy, and discuss two modifications that involve centralized and distributed selection of...
The IEEE 802.15.4 specification is a recent low data rate wireless personal area network standard. While basic security services are provided for, there is a lack of more advanced techniques which are indispensable in modern personal area network applications. In addition, performance implications of those services are not known. In this paper, we describe a secure data exchange protocol based on...
