Abstract
Combinatorial auction with flexible bidding formats is
proposed in this paper for the channel allocation problem
in cognitive radio networks. Different from other auction
mechanisms, our solution includes the channel
characteristic and user requirements in the biding, and
therefore has more freedom to reflect the preference of
secondary users on the channel selection. Four bidding
formats are introduced, each of which has different
emphasis to maximize social welfare of the spectrum
resource. The details of each bidding format are
explained, followed by the optimal solution or
approximation solution proposed for each format. The
approximation ratio of proposed algorithms is analyzed.
Finally a numerical test is conducted in terms of social
welfare and spectrum utilization. The test shows that
actual approximation ratio is close to the optimal one
