A predictive strategy for lifetime maximization in selective relay networks
(
IEEE
, 2009 , Conference Paper)
Two algorithms based on an energy conserving dynamic transmit power threshold are proposed for improving the lifetime in relay networks utilizing selective relay strategies with amplify-and-forward (AF) relays. the lifetime ...
To Relay or Not To Relay in Cognitive Radio Sensor Networks
(
IEEE
, 2014 , Article)
A recent investigation on MAC layer in cognitive radio networks proposed the primary packet relaying by the secondary node maintaining an extra queue used for this particular addable functionality. Nevertheless, relaying ...
Performance analysis of general order selection in decentralized cognitive radio networks
(
IEEE
, 2014 , Conference Paper)
In this paper, we consider an underlay secondary network comprising of K transmitter-receiver pairs sharing the spectrum of a primary network, which is divided into n non-overlapping frequency bands (subchannels). Each ...
