Cognitive radio communication can opportunistically access underutilized spectrum for
emerging wireless applications. With interweave cognitive implementation, a secondary …

Due to exponential growth in the number of wireless devices, with each one exchanging
huge amount of data, requirement for the spectrum in almost all bands has risen very …

Based on cross-layer design, a modified 2-dimensional queuing model (2DQM) is proposed
in this paper to tackle the problem of end-to-end quality of service (QoS) metric calculation …

Le vieillissement de la population sans doute catalysera l'augmentation des maladies
chroniques et intensifiera le besoin de solutions d'assistance à la personne. Pendant que …

In cognitive radio networks, a secondary user (SU) is dependent upon the spectrum, of
varied frequency, temporarily vacated by primary users (PU) thereby making it quite a …

Cognitive radio transceiver can opportunistically access the underutilized spectrum resource
of primary systems for new wireless services. With interweave cognitive implementation …

In cognitive radio communication, unlicensed secondary user (SU) can access under-
utilized spectrum of the licensed primary user (PU) opportunistically for emerging wireless …

We investigate the statistics of transmission time of wireless systems employing adaptive
transmission. Unlike traditional transmission systems where the transmission time of a fixed …

A key challenge for the wireless community is efficiently sharing wireless spectrum and
supporting coexistence for the growing number and density of wireless devices. Dynamic …
