This paper presents HyperBone, an overlay network based on a virtual hypercube that offers services such as monitoring and routing, allowing the execution of distributed applications across the Internet. Hypercubes are scalable by definition, presenting several properties such as symmetry and logarithmic diameter, that are advantageous for distributed and(More)
This work introduces the Distributed Network Reachability (DNR) algorithm, a distributed system-level diagnosis algorithm that allows every node of a partitionable arbitrary topology network to determine which portions of the network are reachable and unreachable. DNR is the first distributed diagnosis algorithm that works in the presence of network(More)
Growing concerns with environmental issues have resulted in alternatives for urban mobility and public transportation. Among the available options, battery-powered electric buses have been considered in terms of flexibility, sustainability, and emission of pollutants. These buses have a plug-in recharge system that allows them to run without any extra power(More)
Complex networks have been used to model public transportation systems (PTS) considering the relationship between bus lines and bus stops. Previous works focused on statistically characterize either the whole network or their individual bus stops and lines. The present work focused on statistically characterize different regions of a city (Curitiba, Brazil)(More)
