Papers accepted for publication


I am very happy to announce the acceptance of two of our paper in the 10th International Conference on Circuits and Systems Technologies (MOCAST 2021).

The first paper, entitled “Pathloss modeling for in-body optical wireless communications” presents an experimental-based novel general path loss model for in-body optical wireless communications (OWCs). In more detail, we used experimental measurements in order to extract analytical expressions for the absorption coefficients of the five (5) main tissues’ constitutions, namely oxygenated and de-oxygenated blood, water, fat, and melanin. Building upon these expressions, we extracted a general formula for the absorption coefficient evaluation of any biological tissue. To verify the validity of this formula, we computed the absorption coefficient of complex tissues and compare them against respective experimental results reported by independent research works. Our results verified the accuracy of the pathloss framework. We strongly believe that this model will become the pillar for several analytical as well as experimantal studies and will eventually open the door in designing & developing innovative in-body OWC system architectures as well as their corresponding transmission/reception schemes.

The second paper, entitled “Dual-hop Blockchain Radio Access Networks for Advanced Coverage Expansion,” which have as the first author a undergraduate student of the Department of Electrical and Electronic Engineering at the University of Western Macedonia, Greece, who conducts his diploma dissertation on this topic, introduces a dual-hop blockchain radio access network (DH-BRAN) topology for dynamic coverage expansion. To analyze the performance of this topology, we present the theoretical framework that captures the characteristics of the proposed topology. Building upon it, the performance of the DH-BRAN, in terms of latency and waiting probability, are quantified. Our results reveal that DR-BRAN can be employed in several realistic use-cases and that there exists a trade-off between latency and security. We are very proud for this contribution, as in our opinion, it set the stage of enabling access through non-comercial intermediate wireless nodes.

I would like to thank all my co-authors for their contributions and hard work!
