Auction mechanisms for distributed spectrum sharing
Jianwei Huang, Randall Berry, Michael L. Honig · 2004
We study auction mechanisms for allocating power among a group of spread spectrum users. The users are assumed to share the bandwidth with a licensed user, or spectrum owner, which imposes a received power constraint (corresponding to a constraint on interference) at a particular measurement location. Both colocated and non-collocated receivers are considered. Each user receives a utility that is a function of the received Signal-to-Interference plus Noise Ratio. We propose two auction mechanisms for power allocation in which the spectrum owner charges for SINR and received power, respectively, and compare the associated utility and revenue achieved in some simple cases. We also derive an iterative and distributed bid updating algorithm, and specify conditions for which this algorithm converges globally to the NE of the auction. 1
