LearningCity: Knowledge Generation for Smart Cities
Dimitrios Amaxilatis, Georgios Mylonas, Evangelos Theodoridis +2
Although we have reached new levels in smart city installations and systems, efforts so far have focused on providing diverse sources of data to smart city services consumers while…
Managing smartphone crowdsensing campaigns through the Organicity smart city platform
Dimitrios Amaxilatis, Evangelos Lagoudianakis, Georgios Mylonas +1
We briefly present the design and architecture of a system that aims to simplify the process of organizing, executing and administering crowdsensing campaigns in a smart city conte…
Knowledge co-creation in the OrganiCity: Data annotation with JAMAiCA
Aikaterini Deligiannidou, Dimitrios Amaxilatis, Georgios Mylonas +1
Numerous smart city testbeds and system deployments have surfaced around the world, aiming to provide services over unified large heterogeneous IoT infrastructures. Although we hav…
Exact size counting in uniform population protocols in nearly logarithmic time
David Doty, Mahsa Eftekhari, Othon Michail +2
We study population protocols: networks of anonymous agents that interact under a scheduler that picks pairs of agents uniformly at random. The _size counting problem_ is that of c…
How Many Cooks Spoil the Soup?
Othon Michail, Paul G. Spirakis
In this work, we study the following basic question: "How much parallelism does a distributed task permit?" Our definition of parallelism (or symmetry) here is not in terms of spee…
Connectivity Preserving Network Transformers
Othon Michail, Paul G. Spirakis
The Population Protocol model is a distributed model that concerns systems of very weak computational entities that cannot control the way they interact. The model of Network Const…
Determining Majority in Networks with Local Interactions and very Small Local Memory
George B. Mertzios, Sotiris E. Nikoletseas, Christoforos L. Raptopoulos +1
We study here the problem of determining the majority type in an arbitrary connected network, each vertex of which has initially two possible types. The vertices may have a few add…
Simple and Efficient Local Codes for Distributed Stable Network Construction
Othon Michail, Paul G. Spirakis
In this work, we study protocols so that populations of distributed processes can construct networks. In order to highlight the basic principles of distributed network construction…
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…
Lowest-ID with Adaptive ID Reassignment: A Novel Mobile Ad-Hoc Networks Clustering Algorithm
Damianos Gavalas, Grammati Pantziou, Charalampos Konstantopoulos +1
Clustering is a promising approach for building hierarchies and simplifying the routing process in mobile ad-hoc network environments. The main objective of clustering is to identi…
Clustering of Mobile Ad Hoc Networks: An Adaptive Broadcast Period Approach
Damianos Gavalas, Grammati Pantziou, Charalampos Konstantopoulos +1
Organization, scalability and routing have been identified as key problems hindering viability and commercial success of mobile ad hoc networks. Clustering of mobile nodes among se…
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…
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…
