Special Issue Information

Dear Colleagues,

The communication model of the Internet of Things has gained an important space within telecommunications and data science, due to its applications and versatility. IoT systems allow information to be obtained from all things, and to control various types of processes using actuators and sensors. This has encouraged researchers from different fields of electronics and computing engineering to offer alternatives and mechanisms for an intelligent, efficient, reliable, and secure deployment of the IoT through networking solutions that guarantee its availability.

In this Special Issue, we focus on the resilience of IoT systems. Resilience can be defined as the ability of certain systems to recover and continue to function after being affected by an unexpected event. In IoT, resilience involves not only networking aspects but also the applications that facilitate deployment of the offered services. For example, the networks that connect the devices in the IoT are exposed to different and unexpected events, the same ones that can alter their operation and even stop transmitting if they do not have the automatic reconfiguration characteristics, interrupting the data collection process and device control.

Considering this situation, for this Special Issue, we seek proposals focused on resilience in IoT networks, offering systems that are smart enough to reconfigure after unexpected events, maintaining the availability of IoT service.

We invite submissions related to resilient IoT solutions, including but not limited to:

Reconfigurable sensor networks
Opportunistic networks (OppNets)
Delay Tolerant Networks (DTN)
IoT based on OppNets and DTN
Resilient in long-range and short-range topologies
Security issues in IoT
IoT without Internet
Hybrid IoT infrastructures
Smart vehicular networks supporting IoT
Simulation and modeling IoT protocols
Smart devices and services
Novel wireless standards (LoRa, SigFox, etc.)
Intelligent routing for IoT
Green computing
Fog computing
Smart collaboration for IoT
Autonomic computing for smart cities

Abstract

Healthcare professionals and scholars have emphasized the need for IoT-based remote health monitoring services to track the health of the elderly. Such systems produce a large amount of data, necessitating the security and privacy of that data. On the other hand, Software Defined Networking (SDN) integration could be seen as a good solution to guarantee both flexibility and efficiency of the network which is even more important in the case of healthcare monitoring. Furthermore, Blockchain has recently been proposed as a game-changing tool that can be integrated into the Internet of Things (IoT) to have the optimal level of security and privacy. However, incorporating Blockchain into IoT networks, which rely heavily on patients’ health sensors, is extremely difficult. In this paper, a secure Healthcare Monitoring System (HMS) is proposed with a focus on trust management issues. The architecture seeks to protect multiple healthcare monitoring system components and preserves patient privacy by developing a security interface where separate security modules can be integrated to run side by side to ensure reliable HMS. The security framework architecture we propose takes advantage of the blockchain technology as a secure and timely information back-end. STHM is a proposal that uses Software-Defined Networking (SDN) as the communication medium that allows users to access SDN’s different functional and security technologies and services. Simulation results show that the use of Blockchain for the SDN-based healthcare monitoring can ensure the desired flexibility and security for a very lightweight additional overhead. Full article
