Architecting the IoT Paradigm: A Middleware for Autonomous Distributed Sensor Networks

Abstract

Actualizing Internet of Things undoubtedly constitutes a major challenge of modern computing and is a promising next step in realizing the unification of all seamlessly interacting entities, either human users or participating machines, under a shared, coherent architecture. While it has now become common belief that the related solutions should be based on compatible network infrastructure employing widely accepted communication schemes, the specifics of the intermediate system that would act as global interface for all involved "things" are yet to be determined. A rising trend to define such machine-based entities is through cyberphysical systems, in terms of collaborating elements with physical input and output. Certainly, sensor networks constitute the most representative realization of such systems. Taking these issues and opportunities under consideration, this work proposes a bioinspired distributed architecture for an Internet of Things that exhibits self-organization properties to enable efficient interaction between entities modeled as cyber-physical systems, mainly focusing on sensor networks. Furthermore, a middleware has been implemented according to the proposed architecture, which serves the role of the backbone of this network as a multiagent and autonomous distributed system. The evaluation results demonstrate the self-optimization properties of the introduced scheme and indicate global network convergence.

Precision Agriculture: A Remote Sensing Monitoring System Architecture

“…However, the farmer can mainly see the current data of the monitored variables of one or all the WSN nodes and consult the history. The interaction with the network and services layer is achieved using an intermediate layer of management logic [36]. WSN data will be stored in an online database [37].…”

Network Protocols, Schemes, and Mechanisms for Internet of Things (IoT): Features, Open Challenges, and Trends

“…Xively aims to provide developers and companies with the ability of integrating all their useful data (collected and produced by physical devices) into other systems in a simple way. Attempts have also been made in the field of autonomous distributed sensor networks to provide efficient middleware solutions, as the one presented in [32]. Moreover, closer to experimental implementation, OpenRemote and Kaa are two well-known and widely used open source middleware platforms.…”

DART: Fast and Efficient Distributed Stream Processing Framework for Internet of Things

“…In their work [3], Eleftherakis and others proposed a distributed and autonomous sensor network architecture for IoT that was inspired by bio-organisms using middleware, which acts as a system for agents to communicate through messages. Their suggested use of this middleware is the main part of their view of an IoT architecture that interacts and manages "things" typically without human interaction.…”
