Optimal cooperative cognitive relaying and spectrum access for an energy harvesting cognitive radio: Reinforcement learning approach
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we consider a cognitive setting under the context of cooperative communications, where the cognitive radio (CR) user is assumed to be a self-organized relay for the network. The CR user and the primary user ...
Stability and delay analysis for cooperative relaying with multi-access transmission
(
Springer Verlag
, 2015 , Conference Paper)
We consider a cooperative relaying system with two source terminals, one full duplex relay, and a common destination. Each terminal has a local traffic queue while the relay has two relaying queues to store the relayed ...
Throughput of a cooperative energy harvesting secondary user in cognitive radio networks
(
Wiley Blackwell
, 2016 , Article)
This paper investigates the maximum throughput of a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU). The SU is assumed to be an energy harvesting node, which harvests energy packets from the ...
Location privacy preservation in secure crowdsourcing-based cooperative spectrum sensing
(
Springer International Publishing
, 2016 , Article)
Spectrum sensing is one of the most essential components of cognitive radio since it detects whether the spectrum is available or not. However, spectrum sensing accuracy is often degraded due to path loss, interference, ...
