Truthful Spectrum Auctions With Approximate Revenue

In cellular networks, a recent trend is to make spectrum access dynamic in the spatial and temporal dimensions, for the sake of efficient utilization of spectrum. In such a model, the spectrum is divided into channels and periodically allocated to competing base stations using an auction-based market mechanism. An "Efficient" auction mechanism is essential to the success of such a dynamic spectrum access model. Two of the key objectives in designing an auction mechanism are "Truthfulness" and revenue maximization.
