Enhancing an eco-driving gamification platform through wearable and vehicle sensor data integration
Christos Tselios, Stavros Nousias, Dimitris Bitzas +5
As road transportation has been identified as a major contributor of environmental pollution, motivating individuals to adopt a more eco-friendly driving style could have a substan…
On the design of a Fog computing-based, driving behaviour monitoring framework
Dimitrios Amaxilatis, Christos Tselios, Orestis Akrivopoulos +1
Recent technological improvements in vehicle manufacturing may greatly improve safety however, the individuals' driving behaviour still remains a factor of paramount importance wit…
Naming and Counting in Anonymous Unknown Dynamic Networks
Othon Michail, Ioannis Chatzigiannakis, Paul G. Spirakis
In this work, we study the fundamental naming and counting problems (and some variations) in networks that are anonymous, unknown, and possibly dynamic. In counting, nodes must det…
Causality, Influence, and Computation in Possibly Disconnected Dynamic Networks
Othon Michail, Ioannis Chatzigiannakis, Paul G. Spirakis
In this work, we study the propagation of influence and computation in dynamic distributed systems. We focus on broadcasting models under a worst-case dynamicity assumption which h…
Deployment and Evaluation of a 802.15.4 Heterogeneous Network
Orestis Akribopoulos, Vasileios Georgitzikis, Christos Koninis +2
In this work we study the performance of a heterogeneous wireless sensor network which consists of 4 different hardware platforms (TelosB, SunSPOT, Arduino, iSense). All hardware p…
Passively Mobile Communicating Logarithmic Space Machines
Ioannis Chatzigiannakis, Othon Michail, Stavros Nikolaou +2
We propose a new theoretical model for passively mobile Wireless Sensor Networks. We call it the PALOMA model, standing for PAssively mobile LOgarithmic space MAchines. The main mo…
The Dynamics of Probabilistic Population Protocols
Ioannis Chatzigiannakis, Paul G. Spirakis
We study here the dynamics (and stability) of Probabilistic Population Protocols, via the differential equations approach. We provide a quite general model and we show that it incl…
Energy and Time Efficient Scheduling of Tasks with Dependencies on Asymmetric Multiprocessors
Ioannis Chatzigiannakis, Georgios Giannoulis, Paul G. Spirakis
In this work we study the problem of scheduling tasks with dependencies in multiprocessor architectures where processors have different speeds. We present the preemptive algorithm…
