Intelligently Wireless Batteryless RF-Powered Reconfigurable Surface
Iosif Vardakis, Georgios Kotridis, Spyridon Peppas +3
This work exploits commodity, ultra-low cost, commercial radio frequency identification tags (RFID) as the elements of a reconfigurable surface. Such batteryless tags are powered a…
Inference-Based Resource Allocation for Multi-Cell Backscatter Sensor Networks
Panos N. Alevizos, Aggelos Bletsas
This work studies inference-based resource allocation in ultra low-power, large-scale backscatter sensor networks (BSNs). Several ultra-low cost and power sensor devices (tags) are…
Nonlinear Energy Harvesting Models in Wireless Information and Power Transfer
Panos N. Alevizos, Georgios Vougioukas, Aggelos Bletsas
This work compares different linear and nonlinear RF energy harvesting models, including limited or unlimited sensitivity, for simultaneous wireless information and power transfer…
Limited Feedback Channel Estimation in Massive MIMO with Non-uniform Directional Dictionaries
Panos N. Alevizos, Xiao Fu, Nicholas D. Sidiropoulos +2
Channel state information (CSI) at the base station (BS) is crucial to achieve beamforming and multiplexing gains in multiple-input multiple-output (MIMO) systems. State-of-the-art…
Sensitive and Nonlinear Far Field RF Energy Harvesting in Wireless Communications
Panos N. Alevizos, Aggelos Bletsas
This work studies both limited sensitivity and nonlinearity of far field RF energy harvesting observed in reality and quantifies their effect, attempting to fill a major hole in th…
Multistatic Scatter Radio Sensor Networks for Extended Coverage
Panos N. Alevizos, Konstantinos Tountas, Aggelos Bletsas
Scatter radio, i.e., communication by means of reflection, has been recently proposed as a viable ultra-low power solution for wireless sensor networks (WSNs). This work offers a d…
Scatter Radio Receivers for Extended Range Environmental Sensing WSNs
Panos N. Alevizos, Aggelos Bletsas
Backscatter communication, relying on the reflection principle, constitutes a promising-enabling technology for lowcost, large-scale, ubiquitous sensor networking. This work makes…
Inference-Based Distributed Channel Allocation in Wireless Sensor Networks
Panos N. Alevizos, Efthymios A. Vlachos, Aggelos Bletsas
Interference-aware resource allocation of time slots and frequency channels in single-antenna, halfduplex radio wireless sensor networks (WSN) is challenging. Devising distributed…
A Simple Cooperative Diversity Method Based on Network Path Selection
Aggelos Bletsas, Ashish Khisti, David P. Reed +1
Cooperative diversity has been recently proposed as a way to form virtual antenna arrays that provide dramatic gains in slow fading wireless environments. However most of the propo…
