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 ... -
On the coexistence of a primary user with an energy harvesting secondary user: A case of cognitive cooperation
( John Wiley and Sons Ltd , 2016 , Article)In this paper, we consider a cognitive scenario where an energy harvesting secondary user shares the spectrum with a primary user. The secondary source helps the primary source in delivering its undelivered packets during ... -
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 ... -
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 ... -
Stability analysis of unstructured finite volume methods for linear shallow water flows using pseudospectra and singular value decomposition
( Elsevier Ltd , 2016 , Article)The discretization of the shallow water system on unstructured grids can lead to spurious modes which usually can affect accuracy and/or cause stability problems. This paper introduces a new approach for stability analysis ... -
Transmit and receive cooperative cognition: Protocol design and stability analysis
( IEEE Computer Society , 2013 , Conference Paper)In this paper, we investigate the stability of a cooperative cognitive system. We propose a cooperative secondary transmitter-receiver system (CSTR), where, the secondary transmitter (ST) and the secondary receiver (SR) ...
