Green video delivery in LTE-based heterogeneous cellular networks
(2015)In this paper we present an optimization framework that formalizes the inherent trade-off between the user perceived quality of wireless video, and the energy consumption cost of the network. The former is formulated in ... -
Heterogeneous spectrum bands aggregation prototype with cognitive radio capabilities
(2015)This paper presents the design and simulation of an RF prototype that can provide dynamic carrier aggregation (CA) in future cognitive heterogeneous cellular networks including also access to heterogeneous technologies. ... -
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, ... -
Spectrally-efficient cooperative video delivery in 5G Heterogeneous wireless networks
(2016)Heterogeneous cellular networks (HetNets), even in 5G systems, are plagued by the problem of intra cell interference, i.e., a strong interfering transmission from a macro BS (MBS) interferes at all the users associated to ... -
Video delivery over heterogeneous cellular networks: Optimizing cost and performance
(2014)Video delivery to mobile users is one of the largest challenges that network operators face today. In this work we consider a heterogeneous cellular network with storage capable small-cell base stations, and study this ...
