DYNAMIC SPECTRUM ACCESS NETWORKS
, 2009
"... We examine the problem of designing an auction-based market mechanism for dynamic spectrum sharing when there are multiple sellers and multiple buyers. We assume that the sellers are selfish players and focus on an optimal auction mechanism that maximizes the expected payoff or profit of the seller. ..."

Broadcasting in Dynamic Spectrum Access Networks
"... Dynamic spectrum access network or cognitive radio network technology has been well studied more than a decade and numerous precious works have been proposed. Nonetheless, none of the existing works provides broadcasting mechanism for cognitive radio networks that operate on multichannel environment ..."

Cooperative Neighbor Discovery in Dynamic Spectrum Access Networks
"... In dynamic spectrum access networks, neighbor discovery is one of the most challenging tasks and, it becomes more critical when there is no centralized coordinator. Neighbor discovery in a DSA network is normally done by using a common control channel or channel hopping. Since both methods introduce ..."

Bandwidth-Adaptive Waveforms for Dynamic Spectrum Access Networks
"... Abstract—This paper presents a novel solution to the challenge of waveform bandwidth estimation in DySPAN systems using intentionally embedded cyclostationary signatures. Dynamic spectrum access networks (DySPANs) achieve high levels of spectrum use efficiency by exploiting spectrum white spaces, ra ..."

F.: Statistical prediction of spectrum occupancy perception in dynamic spectrum access networks
- In: Proc. IEEE Int’l. Conf. on Comms. (ICC
, 2011
"... Abstract—Cognitive radio nodes of a dynamic spectrum access network monitor the spectrum around them in order to detect and opportunistically exploit temporarily unoccupied spectrum gaps. The overall behavior of the whole network depends on the spectrum occupancy perceived by each node at its local ..."

OFDM Pulse-Shaped Waveforms for Dynamic Spectrum Access Networks
"... Abstract—In dynamic spectrum access networks (DySPANs), users share access to available spectrum while minimizing the likelihood of harmful interference. In this demonstration we present a dynamic spectrum access network which employs a re-configurable orthogonal frequency-division multiplexing (OFD ..."

"... when the channel is under the effect of log-normal shadowing. Specifically we propose a distributed power conserving PU detection architecture and investigate the impact of PU detection accuracy on DSAN performance. We measure DSAN blocking probability as a function of the number of PU channels and ..."
