ABSTRACT
Considering the lack of resources in health centers located in rural zones, a part of Colombian population goes affected by the quality of the health Service received. If this is added the low level socioeconomic of some rural population, it is generated a geographic vulnerability. For that reason in this work is presented a Service Oriented Architecture that has as objective support health centers with low technical resources with technology that allows a physical rehab attention independently of the localization of patient and health professional. By way of this, a distributed system it is proposed, using a dispersed communication media like the internet. It is planned to make a modeling process based on a formal tool like the Petri Nets to assure the definition of the services, assistant dispositive teleoperation and the integration and coordination of the system.
Considerando la falta de recursos en centros de salud ubicados en zonas rurales, una parte de la población colombiana se ve afectada por la calidad del Servicio de Salud recibido. Si se suma el bajo nivel socioeconómico de cierta población rural, se genera una vulnerabilidad geográfica. Por ello en este trabajo se presenta una Arquitectura Orientada a Servicios que tiene como objetivo apoyar centros de salud con bajos recursos técnicos con tecnología que permita una atención física de rehabilitación independientemente de la ubicación del paciente y profesional de la salud. De esta manera, se propone un sistema distribuido, utilizando un medio de comunicación disperso como Internet. Para asegurar la definición de los servicios, el asistente de teleoperación dispositiva y la integración y coordinación del sistema, se planea realizar un proceso de modelización basado en una herramienta formal como las redes de Petri.

ABSTRACT
INTRODUCTION: Patient monitoring will tend to decline in the coming years due to a shortage of physical and human resources in hospitals. Therefore, several studies define alternatives to improve patient monitoring using wireless networks. In these studies, a wireless network is used to transfer data generated by medical sensors without interacting with the traffic in the data network of the hospital. However, this approach should be avoided because there are demands for integration between user applications and patient monitoring. Therefore, this paper defines a patient monitoring system, called Wi-Bio, directed to the establishment of IEEE 802.11 networks that allows traffic generated by user applications. METHODS: The formal validation of Wi-Bio was made through the design of Petri nets, and performance analysis was performed through simulations of the Network Simulator 2 tool. The adoption of this approach is justified by the fact that Petri nets allow verification of logical correctness of the designed systems, while simulations allow behavioral analysis of Wi-Bio in overload scenarios where many patients are monitored. RESULTS: The results confirmed the validity of the designed Petri nets and showed that Wi-Bio is able to accomplish the temporal goals imposed by medical sensors, thereby promoting efficient integration of traffic present in the data network and the patient monitoring network. CONCLUSION: As described, Wi-Bio fulfilled its objectives and motivates future studies aimed at complementing the obtained results.
