Autonomic computing (AC) is a promising approach to meet basic requirements in the design of wireless sensor networks (WSNs), and its principles can be applied to efficiently manage nodes operation and optimize network resources. Middleware for WSNs supports the implementation and basic operation of such networks. In this systematic literature review (SLR) we aim to provide an overview of existing WSN middleware systems that address autonomic properties. The main goal is to identify which development approaches of AC are used for designing WSN middleware system, which allow the self-management of WSN. Another goal is finding out which interactions and behavior can be automated in WSN components. We drew the following main conclusions from the SLR results: (i) the selected studies address WSN concerns according to the self- * properties of AC, namely, self-configuration, self-healing, self-optimization, and self-protection; (ii) the selected studies use different approaches for managing the dynamic behavior of middleware systems for WSN, such as policy-based reasoning, context-based reasoning, feedback control loops, mobile agents, model transformations, and code generation. Finally, we identified a lack of comprehensive system architecture designs that support the autonomy of sensor networking.
Las redes de sensores inalámbricas (WSN) e Internet de las Cosas (IoT) son dos áreas de estudio que comparten entre sí ser una infraestructura de red autónoma, en la cual se interconectan objetos para medir variables físicas y dar solución a problemas en una variedad de escenarios de aplicación, como logística, industria, construcciones inteligentes, seguridad, agricultura, entre otros. Esta semejanza suscita una ambigüedad en el uso que la comunidad académica hace de los términos, WSN e IoT, y hace borrosa la línea de dónde pertenecen las contribuciones que se realizan en cada una de estas áreas. En consecuencia, el objetivo de este artículo es analizar la relación, similitud y diferencias entre WSN e IoT en torno a cinco temas: conceptos, requisitos generales, arquitecturas, aplicaciones y tratamiento de datos. A pesar de que WSN e IoT tienen un origen en común, sus enfoques son diferentes en varios aspectos que permiten aclarar la ambigüedad suscita entre la comunidad académica.
