On the power efficiency for cognitive radio networks with multiple relays
(
IEEE
, 2014 , Conference Paper)
In this paper, we study and analyze cooperative cognitive radio networks with multiple secondary users (SUs). Each SU is considered a prospective relay for the primary user (PU) besides having its own data demand. The ...
Cooperative access in cognitive radio networks: Stable throughput and delay tradeoffs
(
IEEE
, 2014 , Conference Paper)
In this paper, we study and analyze fundamental throughput-delay tradeoffs in cooperative multiple access for cognitive radio systems. We focus on the class of randomized cooperative policies, whereby the secondary user ...
Trading wireless information and power transfer: Relay selection to minimize the outage probability
(
IEEE
, 2014 , Conference Paper)
This paper studies the outage probability minimization problem for a multiple relay network with energy harvesting constraints. The relays are hybrid nodes used for simultaneous wireless information and power transfer from ...
Transmission delay minimization for energy constrained communication in wireless body area sensor networks
(
IEEE
, 2014 , Conference Paper)
Body Area Sensor Networks (BASNs) is a promising technology, which promotes smart and scalable vital sign monitoring of the chronically ill and elderly people live an independent life, besides providing people with quality ...
