In this paper, a novel framework for normative modeling of the spectrum
sensing and sharing problem in cognitive radios (CRs) as a transferable utility
(TU) cooperative game is proposed. Secondary users (SUs) jointly sense the
spectrum and cooperatively detect the primary user (PU) activity for
identifying and accessing unoccupied spectrum bands. The games are designed to
be balanced and super-additive so that resource allocation is possible and
provides SUs with an incentive to cooperate and form the grand coalition.
