Optimizing Data Forwarding from Body Area Networks in the Presence of Body Shadowing with Dual Wireless Technology Nodes
Argyriou, A.; Breva, A. C.; Aoun, M. (2015)In this paper we are concerned with the problem of data forwarding from a wireless body area network (WBAN) to a gateway when body shadowing affects the ability of WBAN nodes to communicate with the gateway. To solve this ... -
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, ... -
Packet skipping and network coding for delay-sensitive network communication
Aoun, M.; Beekhuizen, P.; Argyriou, A.; Denteneer, D.; van der Stok, P. (2012)We provide an analytical study of the impact of packet skipping and opportunistic network coding on the timely communication of messages through a single network element. In a first step, we consider a single-server queueing ... -
Performance evaluation of network coding and packet skipping in IEEE 802.15.4-based real-time wireless sensor networks
Aoun, M.; Argyriou, A.; Van Der Stok, P. (2011)In a number of application domains, the volatility of the monitored environment where Wireless Sensor Networks (WSNs) operate engenders timing constraints on the generation, processing, and communication of sensory data. ... -
Queueing model and optimization of packet dropping in real-time wireless sensor networks
Aoun, M.; Argyriou, A. (2012)We consider the problem of modeling the transmission of real-time data from a single node of a wireless sensor network to the next hop or access point. Generated packets are placed in a single position buffer and are ... -
Scalable 3D video streaming over P2P networks with playback length changeable chunk segmentation
Liu, Y.; Liu, J.; Song, J.; Argyriou, A. (2015)3D video distribution over P2P networks has been thought as a promising way for 3D video entering home. The convergence of scalable 3D video coding and P2P streaming can provide diverse 3D experiences for heterogeneous ... -
Transmission of correlated Gaussian sources with opportunistic interference
Alay, O.; Argyriou, A. (2014)Interfering transmissions of independent sources is shown to provide benefits at a cost of complex receiver design. In this paper, we study the optimum transmission of correlated Gaussian sources by allowing opportunistic ... -
Video delivery over heterogeneous cellular networks: Optimizing cost and performance
Poularakis, K.; Iosifidis, G.; Argyriou, A.; Tassiulas, L. (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 ... -
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. ... -
Wireless video transmission with over-the-air packet mixing
Argyriou, A. (2012)In this paper, we propose a system for wireless video transmission with a wireless physical layer (PHY) that supports cooperative forwarding of interfered/superimposed packets. Our system model considers multiple and ...
