Temporal network optimization subject to connectivity constraints

GB Mertzios, O Michail, PG Spirakis - Algorithmica, 2019 - Springer
In this work we consider temporal networks, ie networks defined by a labeling λ λ assigning
to each edge of an underlying graph G a set of discrete time-labels. The labels of an edge …

Naming and counting in anonymous unknown dynamic networks

O Michail, I Chatzigiannakis, PG Spirakis - Symposium on Self-Stabilizing …, 2013 - Springer
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 …

Causality, influence, and computation in possibly disconnected synchronous dynamic networks

O Michail, I Chatzigiannakis, PG Spirakis - Journal of Parallel and …, 2014 - Elsevier
In this work, we study the propagation of influence and computation in dynamic distributed
computing systems that are possibly disconnected at every instant. We focus on a …

Ephemeral networks with random availability of links: The case of fast networks

EC Akrida, L Gąsieniec, GB Mertzios… - Journal of Parallel and …, 2016 - Elsevier
We consider here a model of temporal networks, the links of which are available only at
certain moments in time, chosen randomly from a subset of the positive integers. We define …

Counting in anonymous dynamic networks: An experimental perspective

GA Di Luna, S Bonomi, I Chatzigiannakis… - Algorithms for Sensor …, 2014 - Springer

On verifying and maintaining connectivity of interval temporal networks

EC Akrida, PG Spirakis - Parallel Processing Letters, 2019 - World Scientific
An interval temporal network is, informally speaking, a network whose links change with
time. The term interval means that a link may exist for one or more time intervals, called …
