TODA: Truthful Online Double Auction for Spectrum Allocation in Wireless Networks

Free registration required

Executive Summary

The spectrum usage by a secondary user often happens in a certain geographical region and in a certain time interval, and the requests often come in an online fashion. Considering the selfish behaviors of primary users and secondary users, it is imperative to design online double spectrum auction methods. The most significant challenge is how to make the online double auction economic-robust (truthful in particular). Unfortunately, existing designs either do not consider the online requests or become untruthful when applied to scenarios when both primary users and secondary users could be selfish. In this paper, the authors address this problem by proposing TODA, a general framework for truthful online double auction for spectrum allocation.
