Towards a Collision-Free WLAN: Dynamic Parameter Adjustment in CSMA/E2CA
Jaume Barcelo, Boris Bellalta, Cristina Cano +3
Carrier Sense Multiple Access with Enhanced Collision Avoidance (CSMA/ECA) is a distributed MAC protocol that allows collision-free access to the medium in WLAN. The only differenc…
Measuring the Hierarchy of Feedforward Networks
Bernat Corominas-Murtra, Joaquín Goñi, Carlos Rodríguez-Caso +1
In this paper we explore the concept of hierarchy as a quantifiable descriptor of ordered structures, departing from the definition of three conditions to be satisfied for a hierar…
Topological reversibility and causality in feed-forward networks
Bernat Corominas-Murtra, Carlos Rodríguez-Caso, Joaquín Goñi +1
Systems whose organization displays causal asymmetry constraints, from evolutionary trees to river basins or transport networks, can be often described in terms of directed paths (…
Diversity, competition, extinction: the ecophysics of language change
Ricard V. Solé, Bernat Corominas-Murtra, Jordi Fortuny
As early indicated by Charles Darwin, languages behave and change very much like living species. They display high diversity, differentiate in space and time, emerge and disappear.…
Statistical Analysis of Global Connectivity and Activity Distributions in Cellular Networks
Adrián López García de Lomana, Qasim K. Beg, G. de Fabritiis +1
Various molecular interaction networks have been claimed to follow power-law decay for their global connectivity distribution. It has been proposed that there may be underlying gen…
