摘要：Dynamic spectrum access technology has attracted
much attention for its capability of improving spectrum efficiency.
For attracting primary users to participate in secondary
spectrum market, an auction was proposed as an alternative for
spectrum trade. Existing auction schemes are either to be
unilateral trade which only supports heterogeneous cognitive
radio networks without guarantee of bid truthfulness, or to be
truthful single-unit auction which only supports homogeneous
channels. Few of them could comprehensively take all aspects
of actual spectrum trade into consideration, such as spectrum
allocation and reusability, channel diversity, and economic property.
A truthful bilateral multiunit auction scheme which has
characteristics of supporting heterogeneous networks (TBMAH)
and polynomial complexity is proposed in this paper. We do
experiments with both simulation and real networks, and the
results show that TBMAH trades more spectrum resources than
TRUST by 13.01% on average.
