A cooperative protocol for video streaming in dense small cell wireless relay networks
Kosmanos, D.; Argyriou, A.; Liu, Y.; Tassiulas, L.; Ci, S. (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 ... -
Joint Time-Domain Resource Partitioning, Rate Allocation, and Video Quality Adaptation in Heterogeneous Cellular Networks
Argyriou, A.; Kosmanos, D.; Tassiulas, L. (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
Argyriou, A.; Kosmanos, D.; Tassiulas, L. (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 ... -
Optimizing video quality in dense small-cell wireless networks with packet overhearing
Kosmanos, D.; Argyriou, A.; Tassiulas, L. (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-aware relay selection in single-carrier and OFDM wireless systems
Kosmanos, D.; Argyriou, A.; Tassiulas, L. (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. ...
