Bridging between two cognitive personal area networks (CPANs) is a fundamental step toward a reliable and efficient routing protocol. In this paper, we describe a bridging protocol for two-hop cognitive networks that use the transmission tax-based medium access control and propose ways to prioritize bridge traffic over that of ordinary nodes in both CPANs. We develop an analytical model based on probabilistic...
In a channel-hopping Cognitive Personal Area Network (CPAN), the main objective of the working channel selection mechanism is to avoid collisions with unpredictable primary user activity. As the result, the manner in which the working channel for the next hop is selected, is among the most important determinants of CPAN piconet performance. In this paper we investigate the performance of two working...
