We consider the design of dynamic spectrum access (DSA) mechanism. Assuming
heterogeneous primary channels with distinct availability statistics unknown to each …

Spectrum auction is considered a suitable approach to efficiently allocate spectrum among
unlicensed users. In a typical spectrum auction, secondary users (SUs) bid to buy spectrum …

Spectrum under-utilization is one of the bottlenecks of the development of wireless
communication, and dynamic spectrum access (DSA) is envisioned as a novel mechanism …

Dynamic spectrum auction is considered as an effective solution to improve spectrum
utilization efficiency in dynamic spectrum sharing networks because it can provide an …

With the increasing demands for radio spectrum, techniques are being explored that would
allow dynamic access of spectrum bands that are under-utilized. In this regard, a new …

Spectrum auctions have been proposed as an effective approach to fairly and efficiently
trade the scarce spectrum resource among wireless users. The most significant challenge of …

In this work, we address competition among autonomous cognitive radios (CRs) which are
competing for frequency bands, and model their interactions. We design auction …

With the ever growing demands for spectrum, authorities (eg, FCC in United States) are
defining ways that allow reallocation of spectrum bands that are under-utilized. In this …

A spectrum auction is a promising approach with respect to efficiently allocating spectrum
among unlicensed users. In this paper, we study the spectrum auction based on the …

In this paper, we propose an auction-based spectrum allocation scheme in a multi-channel
distributed cognitive radio network where primary users are the sellers and secondary users …
