TUC Electrical and Computer Engineering (ECE) School received the IEEE WCNEE 2021 Best Paper Award at the “5th IEEE International Workshop on Wireless Communications and Networking in Extreme Environments (WCNEE) 2021” [July 16, 2021], in the context of the “IEEE International Conference on Distributed Computing in Sensor Systems (DCOSS) 2021”.
V. Papageorgiou, A. Nichoritis, P. Vasilakopoulos, G. Vougioukas and A. Bletsas, "Towards Ambiently Powered Inference on Wireless Sensor Networks: Asynchrony is the Key!", 5th IEEE International Workshop on Wireless Communications and Networking in Extreme Environments (WCNEE), July 2021,
is relevant to design and implementation of a batteryless wireless sensor network (WSN) that functions as a distributed computer, solely powered by ambient energy, harvested from the environment.
The paper offers a first step/proof-of-concept. Distributed matrix inversion and consensus algorithms were demonstrated; each WSN node consisted of a 32-bit microprocessor with an embedded radio, solely powered by solar energy using custom circuitry. The basic idea behind this work is to convert message passing losses among WSN nodes (e.g., due to insufficient energy) and intermittent network operation from a bug to a (useful) feature that accelerates the convergence of the inference algorithms. The work is motivated by our need to get rid of power-hungry server farms, absolutely necessary in current (or future) cloud/edge/fog computing, that pollute the environment.
Authors of the paper are the undergraduate ECE students Vasileios Papageorgiou, Athanasios Nichoritis, Panos Vasilakopoulos, the ECE postdoctoral researcher Georgios Vougioukas and Professor Aggelos Bletsas.
IEEE WCNEE 2021 offered totally 2 awards; the 2nd award (best paper award runner-up) was given to University of Rome (La Sapienza).
