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, ...
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 ...
A cooperative protocol for video streaming in dense small cell wireless relay networks
(2015)
The small-cell wireless network (SCN) paradigm is based on the deployment of low-power small cells close to the user so that spatial re-use is increased. Small cell base stations (SCBSs) can be connected either with a wired ...
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. ...
On the implementation of relay selection strategies for a cooperative diamond network
(2013)
In this paper, we present an implementation design of a TDMA protocol for the canonical diamond-topology network containing a source, two relays and a destination (single unicast session). Getting inspired by the established ...
A demonstration of a relaying selection scheme for maximizing a diamond network's throughput
(2012)
We demonstrate a queue-aware algorithm studied in a diamond network topology. This algorithm's decisions are obtained from an analytical optimization framework relying on our technical work [4] and we devise an implementation ...
Joint Time-Domain Resource Partitioning, Rate Allocation, and Video Quality Adaptation in Heterogeneous Cellular Networks
(2015)
Heterogenous cellular networks (HCN) introduce small cells within the transmission range of a macrocell. For the efficient operation of HCNs it is essential that the high-power macrocell shuts off its transmissions for an ...
Optimizing interference cancellation in cooperative wireless networks with relay selection
(2014)
Successive interference cancellation (SIC) is a decoding scheme that allows multiple sources to transmit simultaneously over the wireless medium to a single destination. The power level that each symbol is received has a ...
