Relay-Assisted Primary and Secondary Transmissions in Cognitive Radio Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
We assume a set of cognitive relay nodes that assists both primary and secondary transmissions in a time-slotted cognitive radio networks. To regulate the channel access of the various nodes in the network, we propose an ...
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 ...
On the Design of a Relay-Assisted Network
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
A relay network composed of a source, a set of relays, and a destination is considered. A queueing framework is proposed, in which each node maintains a buffer to store its incoming traffic. An optimization-based formulation ...
On orthogonal band allocation for multiuser multiband cognitive radio networks: Stability analysis
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this work, we study the problem of band allocation of Mi buffered (i.e., with data queues capable of storing incoming traffic packets) secondary users (SUs) to Mp primary frequency bands licensed to (owned by) Mp buffered ...
