BECA: A Blockchain-Based Edge Computing Architecture for Internet of Things Systems
The scale of Internet of Things (IoT) systems has expanded in recent times and, in tandem with this, IoT solutions have developed symbiotic relationships with technologies, such as edge Computing. IoT has leveraged edge computing capabilities to improve the capabilities of IoT solutions, such as facilitating quick data retrieval, low latency response, and advanced computation, among others. However, in contrast with the benefits offered by edge computing capabilities, there are several detractors, such as centralized data storage, data ownership, privacy, data auditability, and security, which concern the IoT community. This study leveraged blockchain’s inherent capabilities, including distributed storage system, non-repudiation, privacy, security, and immutability, to provide a novel, advanced edge computing architecture for IoT systems. Specifically, this blockchain-based edge computing architecture addressed centralized data storage, data auditability, privacy, data ownership, and security. Following implementation, the performance of this solution was evaluated to quantify performance in terms of response time and resource utilization. The results show the viability of the proposed and implemented architecture, characterized by improved privacy, device data ownership, security, and data auditability while implementing decentralized storage
Internet of Things for Mental Health: Open Issues in Data Acquisition, Self-Organization, Service Level Agreement, and Identity Management
The increase of mental illness cases around the world can be described as an urgent
and serious global health threat. Around 500 million people suffer from mental disorders, among
which depression, schizophrenia, and dementia are the most prevalent. Revolutionary technological
paradigms such as the Internet of Things (IoT) provide us with new capabilities to detect, assess,
and care for patients early. This paper comprehensively survey works done at the intersection
between IoT and mental health disorders. We evaluate multiple computational platforms, methods
and devices, as well as study results and potential open issues for the effective use of IoT systems
in mental health. We particularly elaborate on relevant open challenges in the use of existing IoT
solutions for mental health care, which can be relevant given the potential impairments in some
mental health patients such as data acquisition issues, lack of self-organization of devices and service
level agreement, and security, privacy and consent issues, among others. We aim at opening the
conversation for future research in this rather emerging area by outlining possible new paths based
on the results and conclusions of this work.Consejo Nacional de Ciencia y Tecnologia (CONACyT)Sonora Institute of Technology (ITSON) via the PROFAPI program
