Distributed and proximity-constrained C-means for discrete coverage control
Oliva, G.; Gasparri, A.; Fagiolini, A.; Hadjicostis, Christoforos N. (Institute of Electrical and Electronics Engineers Inc., 2018)In this paper we present a novel distributed coverage control framework for a network of mobile agents, in charge of covering a finite set of points of interest (PoI), such as people in danger, geographically dispersed ...

Distributed asynchronous Cholesky decomposition
Oliva, G.; Setola, R.; Hadjicostis, Christoforos N. (Institute of Electrical and Electronics Engineers Inc., 2016)The Cholesky decomposition represents a fundamental building block in order to solve several matrix-related problems, ranging from matrix inversion to determinant calculation, and it finds application in several contexts, ...

Distributed C-means data clustering algorithm
Oliva, G.; Setola, R.; Hadjicostis, Christoforos N. (Institute of Electrical and Electronics Engineers Inc., 2016)In this paper we provide a distributed and asynchronous implementation of the C-means data clustering algorithm to let the agents in a sensor network partition themselves based on the observations available at each node ...

Distributed Calculation of Edge-Disjoint Spanning Trees for Robustifying Distributed Algorithms against Man-in-the-Middle Attacks
Oliva, G.; Cioaba, S.; Hadjicostis, Christoforos N. (2017)In this paper we provide a distributed methodology to allow a network of agents, tasked to execute a distributed algorithm, to overcome Man-in-the-middle attacks that aim at steering the result of the algorithm towards ...

Distributed cycle detection and removal
Oliva, G.; Setola, R.; Glielmo, L.; Hadjicostis, Christoforos N. (2018)In this paper, we provide distributed algorithms to detect and remove cycles in a directed relational graph by exploiting the underlying undirected communication graph; the relational graph models a relation among the ...

Distributed finite-time average-consensus with limited computational and storage capability
Oliva, G.; Setola, R.; Hadjicostis, Christoforos N. (2017)Consensus is a fundamental feature of distributed systems, and it is the prerequisite for several complex tasks, such as flocking of mobile robots, localization in wireless-sensor networks, or decentralized control of smart ...

Distributed finite-time calculation of node eccentricities, graph radius and graph diameter
Oliva, G.; Setola, R.; Hadjicostis, Christoforos N. (2016)The distributed calculation of node eccentricities, graph radius and graph diameter are fundamental steps to tune network protocols (e.g., setting an adequate time-to-live of packets), to select cluster heads, or to execute ...
