Performance of a Cognitive MAC Protocol with Transmission Tax
Vojislav B. Mišić, Jelena Mišić · 2010
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 channels to be sensed.
