La señal es muy inestable y presenta importantes niveles de ruido; es fuertemente afectada por las condiciones del entorno y de los mismos dispositivos. En este artículo, en primer lugar se caracterizan experimentalmente diferentes condiciones de este ruido, luego se analizan distintas parametrizaciones del filtro de media móvil simple, para estabilizar y suavizar la señal; finalmente, se calcula mediante el Óptimo de Pareto, el valor de ventana que hace las veces de punto de equilibro para todos los datasets analizados. Los resultados experimentales muestran que el filtro de media móvil tiene notables beneficios al estimar la distancia a partir de la señal RSSI. Palabras Clave-RSSI, Bluetooth, filtros de señal, media móvil, sistemas de posicionamiento en interiores.

Para lo cual se utilizó el API (Application Programming Interface) de la red social que recoge datos de posibles puntos de congestión vehicular, mediante herramientas de Big Data. Los datos obtenidos son correlacionados con información obtenida mediante sensores de flujo vehicular, para su posterior análisis lo cual permitió identificar situaciones de congestión vehicular.

So the current situation of the city is analyzed as well as the problem that traffic represent for Quito, subsequently the analysis of various cases throughout the world who have suffered the problem of traffic congestion is summarized and then is analized and related with solutions that have been taken and which have improved mobility in these cities. While the focus of this study is not to provide direct solutions to the problem of transportation but rather to present the diagnosis of the main problems. The study deepens with field research with 95% confidence to a total of 384 people by random cluster sampling, seeking to make a representative study of the population that is transported in Quito through a poll. The results determined that the population considers congestion as one of the main problems of the city. Meanwhile in research the perception of the population is presented about the various problems that generate traffic in the city. The vehicular increase and the lack of public transport use are analyzed as part of the results and finally the feasibility of using tools such as social networking identified as potential tools to capture information that allows analyzing alternative solutions to traffic congestion. The study concludes with an analysis of both the main problems and potential solutions to improve traffic and the feasible use of social network Twitter as a tool for decision making for better efficiency of traffic by better use of routes by transportation means as vehicles, achieving research with an initial analysis, but critical to the implementation of potential solutions for decision making in improving traffic congestion in the city.

To succeed in developing software should have a high commitment of the development team, expensive resources, highly trained specialists and processes and increasingly formal methods. The models at different levels of abstraction arise in order to expedite the process of building software, which is focused movement on the use of models at different levels of abstraction. There are some important proposals in this regard those as Model Driven Architecture and Model Driven Software Development .This paper reviews the literature about these two proposals. Describe the fundamental principles aimed at shaping the theoretical basis of the two proposals and the main tools that implement model-driven development for mobile application development work. Describe the fundamental principles aimed at shaping the theoretical basis of the two proposals and the main tools that implement model-driven development for mobile application development work. Also analyzed the importance of Metamodels and possible transformations to generate auto code.

Currently, there are building approaches for this kind of applications, but these do not have the flexibility, for example, to derive applications combining different location sensing mechanisms. In this paper, we present a first proposal of a taxonomy of factors that could be considered by context-aware mobile application building approaches, in order to provide variability in the kinds of derived applications. The aim is to generate a discussion that can contribute to the unification of aspects that should be addressed by these building approaches. To complement the taxonomy, we present the analysis of an interview that was conducted with regard to developers who use (or could use) these building approaches. We hope this will enrich the discussion in relation to this kind of approaches.

This problem causes traffic congestion and influence in the delay of people to get to their jobs. With the advent of smart cities and buildings, research in this area is increasingly relevant. This work proposes a distributed architecture of a real time system for the detection of vacant space in parking lots, using computerized vision and machine learning. The proposed architecture seeks to minimize the search time for a parking space, as well as reduce the congestion resulting from having to maneuver in small spaces with pedestrians. The expected benefits are mainly the reduction of delays in reaching the position of work and study, and the risk reduction of pedestrians circulating in the parking areas, all this with a minimum investment

There are several ways and methods to monitor free parking areas. The method used in this work used surveillance cameras in order to reduce costs because the institution already has its own surveillance system. The first phase of the system corresponds to the development of the application server, which will manage the data and information of all the parking spaces and retrieve the states of these to show them to the end user and also to share them with the module of the mobile application. The server is built in Java using REST API and was assembled inside a Payara server, with a security module based on a token to avoid non-scalability of the application. The second phase of the system is focused on the user so that it has ease of use and can be administered quickly as it is the goal of the sys...

A typical driver invests a considerable part of the total trip time looking for a free space where to park his vehicle; in many cases, this leads to delays and the consequent discomfort due to the undesired consequences of the generated tardiness. For this problem it is possible to find partial palliative solutions, minimizing the time spent searching for parking by applying Internet of Things techniques, oriented to smart cities and buildings. This research has been focused on finding an appropriate computer architecture that will allow the implementation of a distributed system, which, thanks to the use of computer vision and machine learning techniques, detects free parking spaces inside a parking lot, and provides real time information to the driver, allowing him to go as directly as possible to a vacant parking space.
