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 ...
Impact of location heterogeneity on random walk mobility models
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
This paper investigates random walk mobility models with location heterogeneity, where different locations may have different neighboring regions.With the assumption of totally n locations, we consider two cases, i.e., ...
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 ...
Capacity and delay analysis for data gathering with compressive sensing in wireless sensor networks
(2013 , Article)
Compressive sensing (CS) provides a new paradigm for efficient data gathering in wireless sensor networks (WSNs). In this paper, with the assumption that sensor data is sparse we apply the theory of CS to data gathering ...
