Coalitional double auction for spatial spectrum allocation in cognitive radio networks
(
IEEE
, 2014 , Article)
Recently, many dynamic spectrum allocation schemes based on economics are proposed to improve spectrum utilization in cognitive radio networks (CRNs). However, existing mechanisms do not take into account the economic ...
Detecting the greedy spectrum occupancy threat in cognitive radio networks
(
IEEE Computer Society
, 2014 , Conference Paper)
Recently, security of cognitive radio (CR) is becoming a severe issue. There is one kind of threat, which we call greedy spectrum occupancy threat (GSOT) in this paper, has long been ignored in previous work. In GSOT, a ...
Cooperative spectrum sharing in cognitive radio networks: A distributed matching approach
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
We study the relay-based communication schemes for cooperative spectrum sharing among multiple primary users (PUs) and multiple secondary users (SUs) with incomplete information. Inspired by the matching theory, we model ...
