Adapted smart home services based on smart contracts and service level agreements

Abstract

In smart home systems (SHS), devices intercommunicate to create an intelligent environment that can monitor the inhabitant's health state and provide adapted services.However, existing health monitoring systems (HMS) do not provide adapted services to the patient autonomy degree. Furthermore, in these critical systems, the Quality of Service (QoS) aspect is very important; therefore, service level agreements (SLA) are the best solution to define and guarantee the expected QoS levels, nevertheless, existing SLA specification languages lack expressiveness in terms of user preference specification, dynamic service management and pricing. In this work, we propose an elderly health state-aware SHS to offer adapted services according to the elderly health state, it is based on three main parts: (a) the functional autonomy measurement system (SMAF) for calculating the inhabitant's profile or autonomy degree, (b) domain-specific language (DSL) for SLA that aims to increase patient-awareness through the use of preferences, facilitate the SLA management using microservices, and manage the QoS dynamically using multilevel SLA (ML-SLA) concept, and (c) smart contracts for the provision of adapted services and the verification of SLA terms.

Real-Time Home Energy Management with IoT and Blockchain

“…In [7], a new energy management method for smart buildings, which combined a low-energy Bluetooth wireless network for communication between domestic appliances with the development of a HEMS, was presented. In [8], a new smart home design, based on the Resource Name Service (RES), was proposed. However, none of the previous works considered a renewable energybased system.…”

A Preference-Driven Smart Home Service for the Elderly’s Biophilic Experience

“…Technical elements include various types of sensors, devices, and monitoring systems, along with a central control hub. However, despite various technological convergences, the scope of SHS provision for the elderly focuses on supporting energy efficiency and physical functions, such as indoor environment control and automation [ 44 , 53 , 54 , 55 ]. However, despite various technological convergences, the scope of SHS provision for the elderly focuses on supporting energy efficiency and physical functions, such as indoor environment control, automation [ 46 , 47 , 48 , 49 ], and remote response in case of emergency [ 42 , 43 ].…”

A survey: Making “Smart Contracts” really smart

“…After explaining how Blockchain technology and smart contracts work in a way that does not require coding knowledge to understand, they are aimed to contribute to the Turkish literature on this subject by including three application examples in the field of health. 75 Staifi and Belguidoum 76 have worked on smart home systems and proposed a smart home system based on smart contracts sensitive to elderly health status. Chu et al, 77 have studied what Blockchain technology is, the structure and functioning of smart contracts, and the status of smart contracts in the future.…”
