En esta tesis se plantea un doble problema. Por un lado, partiendo de la especificación formal de una protocolo de telecontrol, se desea obtener un análisis de su prestaciones de forma automática, es decir, sin tener que recurrir a métodos clásicos de análisis, sean éstos analíticos o mediante simulación. El segundo problema que se pre tende...

Este documento describe el laboratorio utilizado en las asignaturas de Arquitectura de Redes I y II y Comunicaciones I y II de cuarto de Ingeniería Informática y segundo de Ingeniería Técnica de Gestión para caracterizar el comportamiento de un red ethernet.

Wireless Sensor Networks (WSN) are becoming increasingly important for telemedicine applications, monitoring patients both in the clinical setting and at home. They reduce user discomfort, enhance mobility and reduce costs. WSN are also fundamental in Ambient Assisted Living (AAL) since these smart systems, which are tailored to users...

Este trabajo presenta nuestra experiencia en el desarrollo de una herramienta de simulación de protocolos de nivel MAC basados en el estándar IEEE 802.16 [1]. El empleo de esta herramienta en el laboratorio ayuda a los alumnos en el estudio y comprensión de protocolos de redes de última milla. En particular, se ha definido un protocolo de...

This paper presents the use of ESTELLE, a formal description technique, as a method to calculate automatically the performance of telecontrol protocols in SCADAsystems. Some specific primitives are added to the ESTELLE description language in order to achieve that goal. As an example, we analyze the performance of a telecontrol protocol. The...

Solutions in the field of Ambient Assisted Living (AAL) do not generally use standards to implement a communication interface between sensors and actuators. This makes these applications isolated solutions because it is so difficult to integrate them into new or existing systems. The objective of this research was to design and implement a...

TAIS group has developed an indoor position system prototype based on a fingerprint positioning algorithm. The prototype uses IEEE 802.15.4 mote and BitCloud Stack, a full-featured ZigBee Compliant, second generation embedded software stack from Atmel. The design requirements of the prototype were only to determine the actual position in a room...

En un mundo complejo y cambiante como el nuestro, a veces resulta difícil comprender en profundidad los avances que vivimos y, en ocasiones, no es fácil discernir lo fundamental de lo accesorio. Debemos admitir que el entorno, la historia, la sociología, la teoría de la evolución y la teoría de sistemas... aplicadas al desarrollo del...

La próxima reforma ha hecho que se pongan en práctica experiencias piloto y ensayos de nuevas metodologías de enseñanza aprendizaje. Se podría decir que todos los sectores de la universidad están en un proceso de reflexión que siempre ha existido (ya que no sólo son conocimientos lo que un profesor debe transmitir a los alumnos) pero que ahora...

Since the electric generating, distributing and marketing has been possible; the Electric Meter was introduced and developed along the years, but never like this time. The digital technology, the wireless communication, and the computer systems have dramatically changed the Electric meter generation from Traditional Meter to Automatic Meter and...

This paper presents a proposal of a flexible telemedicine system for remote patient monitoring. It can be used in different kind of environments where there is only available low speed transmission links like Radio Frequency. This proposal includes the use of a previous work where the IEC-60870-S standard was applied to the development of an...

This paper presents a work in progress for the developing of a fingerprint indoor position system based on OpenMAC, an IEEE 802.15.4 embedded software implementation from Atmel to be used in different scenarios like e_health, ambient living or smart building. The system is thought to work as another one that we have yet developed but using the...

This paper presents the development and testing of an open and flexible embedded system applied to positioning and telecontrol (OFESAPO) for outdoor applications. The system is composed of a control center (CC) and a set of remote terminal units (RTUs); the International Electrotechnical Commission (IEC) 60870-5 series has been chosen for...

This paper presents an analysis of the behaviour of an indoor position system based on fingerprints and IEEE 802.15.4 that has been adapted to be tested in a competition, called EvAAL (Evaluating AAL Systems through Competitive Benchmarking), hold both in Madrid (tests) and Eindhoven (results). The objectives of this analysis are to determine...

En este trabajo se presenta la elaboración de una herramienta de simulación que reproduce el comportamiento de un computador simple. Con ello se pretende mejorar la docencia desde dos puntos de vista: por un lado, desde la vertiente del alumno, al cual se le ofrece la posibilidad de trabajar con esta herramienta, incluso en su propia casa;...

Nowadays there is a research on ambient living and smart building applications to make people life more confortable. This kind of applications, in general, requires the position where a person is in a building to act according it and to any physical parameters that are measured from the person, to determine, for instance, if the air condition...

Body Area Networks are a solution to remote monitoring in order to acquire vital signals of patients. Actual sensors provide its own interface which makes more difficult to integrate them in a system. Using standardized protocols and interfaces increases the usability and the integration of different sensors, to achieve this goal the IEEE 1451...

The work described in this paper is focused on the attainment of a product that: a) is able to manage a communication network according to ISO ant ITU-T standards (Telecommunication Management Network, TMN, model); b) automatically locates network faults based on a set of rules embedded in an integrated expert system; and c) represents the...

This paper presents some works made in the development of communications software for an embedded open core system. By using a Linux-based processor implemented on a FPGA, we are developing the appropriate software in order to implement a remote unit to be used in a telecontrol network. We present an analysis of the physical devices needed and...
