Software-Defined Networking (SDN) paradigm has decoupled data and control planes on traditional networks. In this context, a logically-centralized controller, with full knowledge on network resources and traffic loads, executes routing algorithms to identify forwarding paths, while networking resources (switches and routers) just work on packet forwarding. This work contributes by executing and characterizing a well-know distributed application, NAS parallel benchmark, atop an SDN-based data center. A comparison with different flow routing algorithms is presented, highlighting that an application can reduce its runtime when applying a multi-path routing. © 2016 IEEE.

Linelike features in TeV γ rays constitute a “smoking gun” for TeV-scale particle dark matter and new physics. Probing the Galactic Center region with ground-based Cherenkov telescopes enables the search for TeV spectral features in immediate association with a dense dark matter reservoir at a sensitivity out of reach for satellite γ-ray detectors, and direct detection and collider experiments. We report on 223 hours of observations of the Galactic Center region with the MAGIC stereoscopic telescope system reaching γ-ray energies up to 100 TeV. We improved the sensitivity to spectral lines at high energies using large-zenith-angle observations and a novel background modeling method within a maximum-likelihood analysis in the energy domain. No linelike spectral feature is found in our analysis. Therefore, we constrain the cross section for dark matter annihilation into two photons to ⟨σv⟩≲5×10−28 cm3 s−1 at 1 TeV and ⟨σv⟩≲1×10−25 cm3 s−1 at 100 TeV, achieving the best limits to date for a dark matter mass above 20 TeV and a cuspy dark matter profile at the Galactic Center. Finally, we use the derived limits for both cuspy and cored dark matter profiles to constrain supersymmetric wino models.

Clocking represents the manner in which companies register employee data;particularly, data related to entrances to and departures from the company. Being normally implemented with wireless cards or by hand, this procedure can implies on large queues, reducing the emloyee productivity, besides being sensitive to longer complications (when the employee forget to register the clocking, for example). In this context, we developed a model named ACID (Automatic Clocking and Idleness Detection) to bring benefits for both administrators and employees through the use of wireless sensors. Besides eliminating queues, it is possible to analyze those employees that are away from their own places for more than a particular threshold. In addition, the model is also pertinent to enhance decision support when promotions take place. We developed a prototype that was evaluated through simulation, taking into account the architectural plant and the employees behavior of five real Brazilian companies. The results reveals the benefits of using IDAC both at the owner (control and productivity) and employees (the clocking actions occurs automatically) levels. © 2016 IEEE.

35th International Conference of the Chilean Computer Science Society, SCCC 2016

As a result of rural and suburban migration to the cities, urban life has become a significant challenge for citizens and mayors, imposing a huge concern in the sustainable use of resources like energy, water, transportation and housing. Smart cities are the biggest bet to address these challenges efficiently through a real-time monitoring approach which aims to assist in intelligent planning and sustainable urban development. However, to accomplish this monitoring efficiently and to enable the sustainable use of resources, it is necessary an integration between citizens, city devices and the platform where the data is stored and processed. In this context, we are proposing the 3LES model (3 Levels of Energy Saving for Smart Cities), a model that combines data from citizens, city devices and nodes from the processing plataform to offer a multilevel energy saving proposal. 3LES must act transparently without affecting the quality of the services already offered in the city. This paper presents the components of management and monitoring of power consumption at various levels, as well as a model that monitors the energy consumption of elastic cloud applications. The results are promising, with a model that allows the estimation of the energy consumption of elastic applications based on CPU and memory traces with an average and median precision of 97.15% and 97.72%. In addition, we obtained a reduction of more than 90% in the energy spent in public lighting in the city of Rome when analyzing the citizens' location. © 2016 IEEE.

Symbiotic relationships are one of several phenomena that can be observed in nature. These relationships consist of interactions between organisms and can lead to benefits or damages to those involved. In an optimization context, symbiotic relationships can be used to perform information exchange between populations of candidate solutions to a given problem. This paper presents an information exchange model inspired by symbiotic relationships and applies the model to unconstrained single-objective continuous optimization problems. The symbiotic relationships are modelled using the Pareto dominance criteria inside a computational ecosystem for optimization. The Artificial Bee Colony algorithm is used to compound the populations of the ecosystem. Four models of relationships are analyzed: slavery, competition, altruism and mutualism. Thirty unconstrained single-objective continuous benchmark functions with high number of dimensions (d = 200) are tested and obtained results compared. Results suggest that the proposed model for information exchange favors the balance between exploration and exploitation leading to better results.

The fast growing and the aging of the population are some of the major problems today in terms of medical treatment in public or private hospitals. In this context, particularly talking about the health equipments belonging to each hospital, we also observe that governments and administrators still face difficulties in overseeing the tracking, allocation and management of such equipments in real-time. The gap of acquiring a global overview about what each hospital has or not invariably leads to resource wasting in some places, while there is a lacking of resources in others, so providing a deficient service at regional or national scale. Here, we are proposing the EMH (Elastic Multi-hospital Management) model, which uses the cloud elasticity facility to provide a distributed framework for managing things including physical spaces and objects at real-time within the context of multiple healthcare institutions. Our solution consists in offering a centralized management control center that works with cloud elasticity to enlarge or reduce the number of virtual machines to support the variable incoming demands from the hospitals. Thus, the idea is to subsidize real-time decision making in favor of managers who can, for instance, plan expansions, new health policies or equipment exchanges between hospitals. EMH is based on the RFID (Radio-frequency identification) sensor tracking technology, combined with the client-server Web Service concept, to detect motion and usability of objects. Finally, we developed a prototype of the EMH model which emphasized the benefits on providing a unique administration point and handling incoming workload with cloud elasticity to address user requests inside an acceptable response time (here denoted as lower than 200 ms).
