New techniques to integrate blockchain in Internet of Things scenarios for massive data management

Mención Internacional en el título de doctorNowadays, regardless of the use case, most IoT data is processed using workflows that are executed on different infrastructures (edge-fog-cloud), which produces dataflows from the IoT through the edge to the fog/cloud. In many cases, they also involve several actors (organizations and users), which poses a challenge for organizations to establish verification of the transactions performed by the participants in the dataflows built by the workflow engines and pipeline frameworks. It is essential for organizations, not only to verify that the execution of applications is performed in the strict sequence previously established in a DAG by authenticated participants, but also to verify that the incoming and outgoing IoT data of each stage of a workflow/pipeline have not been altered by third parties or by the users associated to the organizations participating in a workflow/pipeline. Blockchain technology and its mechanism for recording immutable transactions in a distributed and decentralized manner, characterize it as an ideal technology to support the aforementioned challenges and challenges since it allows the verification of the records generated in a secure manner. However, the integration of blockchain technology with workflows for IoT data processing is not trivial considering that it is a challenge not to lose the generalization of workflows and/or pipeline engines, which must be modified to include the embedded blockchain module. The main objective of this doctoral research was to create new techniques to use blockchain in the Internet of Things (IoT). Thus, we defined the main goal of this thesis is to develop new techniques to integrate blockchain in Internet of Things scenarios for massive data management in edge-fog-cloud environments. To fulfill this general objective, we have designed a content delivery model for processing big IoT data in Edge-Fog-Cloud computing by using micro/nanoservice composition, a continuous verification model based on blockchain to register significant events from the continuous delivery model, selecting techniques to integrate blockchain in quasi-real systems that allow ensuring traceability and non-repudiation of data obtained from devices and sensors. The evaluation proposed has been thoroughly evaluated, showing its feasibility and good performance.Hoy en día, independientemente del caso de uso, la mayoría de los datos de IoT se procesan utilizando flujos de trabajo que se ejecutan en diferentes infraestructuras (edge-fog-cloud) desde IoT a través del edge hasta la fog/cloud. En muchos casos, también involucran a varios actores (organizaciones y usuarios), lo que plantea un desafío para las organizaciones a la hora de verificar las transacciones realizadas por los participantes en los flujos de datos. Es fundamental para las organizaciones, no solo para verificar que la ejecución de aplicaciones se realiza en la secuencia previamente establecida en un DAG y por participantes autenticados, sino también para verificar que los datos IoT entrantes y salientes de cada etapa de un flujo de trabajo no han sido alterados por terceros o por usuarios asociados a las organizaciones que participan en el mismo. La tecnología Blockchain, gracias a su mecanismo para registrar transacciones de manera distribuida y descentralizada, es un tecnología ideal para soportar los retos y desafíos antes mencionados ya que permite la verificación de los registros generados de manera segura. Sin embargo, la integración de la tecnología blockchain con flujos de trabajo para IoT no es baladí considerando que es un desafío proporcionar el rendimiento necesario sin perder la generalización de los motores de flujos de trabajo, que deben ser modificados para incluir el módulo blockchain integrado. El objetivo principal de esta investigación doctoral es desarrollar nuevas técnicas para integrar blockchain en Internet de las Cosas (IoT) para la gestión masiva de datos en un entorno edge-fog-cloud. Para cumplir con este objetivo general, se ha diseñado un modelo de flujos para procesar grandes datos de IoT en computación Edge-Fog-Cloud mediante el uso de la composición de micro/nanoservicio, un modelo de verificación continua basado en blockchain para registrar eventos significativos de la modelo de entrega continua de datos, seleccionando técnicas para integrar blockchain en sistemas cuasi-reales que permiten asegurar la trazabilidad y el no repudio de datos obtenidos de dispositivos y sensores, La evaluación propuesta ha sido minuciosamente evaluada, mostrando su factibilidad y buen rendimiento.This work has been partially supported by the project "CABAHLA-CM: Convergencia Big data-Hpc: de los sensores a las Aplicaciones" S2018/TCS-4423 from Madrid Regional Government.Programa de Doctorado en Ciencia y Tecnología Informática por la Universidad Carlos III de MadridPresidente: Paolo Trunfio.- Secretario: David Exposito Singh.- Vocal: Rafael Mayo Garcí

The Research Journey as a Challenge Towards New Trends

The academic community of the department of Risaralda, in its permanent interest in evidencing the results of the research processes that are carried out from the Higher Education Institutions and as a product of the VI meeting of researchers of the department of Risaralda held in November 2021 presents its work: “The journey of research as a challenge towards new trends”, which reflects the result of the latest research and advances in different lines of knowledge in Agricultural Sciences, Health Sciences, Social Sciences and Technology and Information Sciences, which seek to solve and meet the demands of the different sectors. This work would not have been possible without the help of each of the teachers, researchers and authors who presented their articles that make up each of the chapters of the book, to them our gratitude for their commitment, dedication and commitment, since their sole purpose is to contribute from the academy and science to scientific and technological development in the search for the solution of problems and thus contribute to transform the reality of our society and communities. We also wish to extend our gratitude to the institutions of the Network that made this publication possible: UTP, UCP, UNAD, UNIREMINGTON; UNISARC, CIAF, Universidad Libre, Uniclaretiana, Fundación Universitaria Comfamiliar and UNIMINUTO, institutions that in one way or another allowed this work to become a reality, which we hope will be of interest to you.Preface............................................................................................................................7 Chapter 1.
