Maximum throughput of a cooperative energy harvesting cognitive radio user
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, we investigate the maximum throughput of a saturated rechargeable secondary user (SU) sharing the spectrum with a primary user (PU). The SU harvests energy packets (tokens) from the environment with a certain ...
Protocol design and stability analysis of cooperative cognitive radio users
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
A single cognitive radio transmitter-receiver pair shares the spectrum with two primary users communicating with their respective receivers. Each primary user has a local traffic queue, whereas the cognitive user has three ...
Maximum throughput of a secondary user cooperating with an energy-aware primary user
(
IEEE Computer Society
, 2014 , Conference Paper)
This paper proposes a cooperation protocol between a secondary user (SU) and a primary user (PU) which dedicates a free frequency subband for the SU if cooperation results in energy saving. Time is slotted and users are ...
Probabilistic band-splitting for a buffered cooperative cognitive terminal
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, we propose a cognitive protocol that involves cooperation between the primary and secondary users. In addition to its own queue, the secondary user (SU) has a queue to store, and then relay, the undelivered ...
