On Designing Truthful Spectrum Auctions for Variable Bandwidths

by Tingting Chen, Sheng Zhong , 2011
"... Dynamic spectrum auctions have been considered a promising approach to effectively re-distribute spectrum resources in the secondary spectrum market. However, the existing spectrum auctions are limited to allocating spectrum in units of channels. Recently software defined radio technologies make ex ..."

exciting progress in operating radios with variable bandwidths. They push the need for designing more flexible spectrum auction frameworks that allow to allocate spectrum with variable bandwidth to the secondary user. In this paper, we design truthful spectrum auction frameworks in which secondary users

Efficient advert assignment

"... Abstract We develop a framework for the analysis of large-scale Ad-auctions where adverts are assigned over a continuum of search types. For this pay-per-click market, we provide an efficient mechanism that maximizes social welfare. In particular, we show that the social welfare optimization can be ..."

Abstract Supporting database schema evolution repre-sents a long-standing challenge of practical and theoretical importance for modern information systems. In this paper, we describe techniques and systems for automating the critical tasks of migrating the database and rewriting the legacy applications. In addition to labor saving, the ben-efits delivered by these advances are many and include reliable prediction of outcome, minimization of downtime, system-produced documentation, and support for archiving, historical queries, and provenance. The PRISM/PRISM++ system delivers these benefits, by solving the difficult prob-lem of automating the migration of databases and the rewrit-ing of queries and updates. In this paper, we present the PRISM/PRISM++ system and the novel technology that made it possible. In particular, we focus on the difficult and previously unsolved problem of supporting legacy queries and updates under schema and integrity constraints evolution. The PRISM/PRISM++ approach consists in providing the users with a set of SQL-based Schema Modification Opera-tors (SMOs), which describe how the tables in the old schema are modified into those in the new schema. In order to sup-port updates, SMOs are extended with integrity constraints
