Performance of G-limited scheduling in a cognitive MAC with transmission tax

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. Extended sensing, however, tends to impair the data transmission performance. In this paper we investigate the performance of G-limited scheduling which ensures satisfactory packet delay for each node, whilst making sure that sufficient sensing is done so as to maintain smooth operation of the CPAN.
