Optimizing video quality in dense small-cell wireless networks with packet overhearing
(2014)
The heterogeneous wireless network (HetNet) paradigm is based on the deployment of low power small cell base stations (SCBS) close to the user in parallel with a macrocell BS (MBS) that provides umbrella coverage. However, ...
Online assessment of sensing performance in experimental spectrum sensing platforms
(2014)
Dynamic Spectrum Access aims at exploiting underutilized frequency bands towards improving wireless network performance. In this context, spectrum sensing is employed, in order to monitor spectrum occupancy and drive ...
The mutual benefits of primary-secondary user cooperation in wireless cognitive networks
(2014)
In cognitive radio networks, secondary users (SUs) may cooperate with the primary user (PU) in order to obtain more transmission opportunities and thus maximize their throughput. The synergy consists in the following: the ...
Dynamic resource provisioning for energy efficiency in wireless access networks: A survey and an outlook
(2014)
Traditionally, energy efficiency aspects have been included in the wireless access network design space only in the context of power control aimed at interference mitigation and for the increase of the terminal battery ...
Video-aware relay selection in single-carrier and OFDM wireless systems
(2014)
In this paper we consider packetized video transmission in cooperative relay-based wireless networks. We propose algorithms for optimized relay selection that take into account the content of each specific video packet. ...
Optimal selfishness-aware device-assisted content delivery in cellular networks
(2014)
Utilization of device-to-device communication links provides an alternative way for mitigating the skyrocketing mobile data growth that challenges cellular operators nowadays. Namely, the owners of these devices can serve ...
Efficient file replication in large wireless networks with dynamic popularity
(2014)
We investigate the problem of replication in large wireless networks that employ caching in the case of a single file whose popularity varies with time. As opposed to the case of static popularity, in this case for the ...
C2M: Mobile data offloading to mesh networks
(2014)
As the unprecedented growth of mobile data traffic places significant strain on cellular networks, alternative plans for exploiting already existing and under-utilized wireless infrastructure, become quite attractive. In ...
