Band allocation for cognitive radios with buffered primary and secondary users
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In this paper, we study band allocation of Ms buffered secondary users (SUs) to Mp orthogonal primary licensed bands, where each primary band is assigned to one primary user (PU). Each SU is assigned to one of the available ... -
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 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 ... -
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 ... -
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) ...
