# A Review of Internet of Things Technologies for Ambient Assisted Living Environments
## 6 Conclusions  
The use of AAL systems and platforms is increasing in line with the growing population of older people. Internet-of-Things (IoT) has emerged as a technological background for implementation of Ambient Assisted Living (AAL). Support for active and independent living requires addressing the main challenges of IoT such as data veracity, integration, interoperability, privacy, reliability, security, and usability.  
Current study analyzed and discussed the following research issues of IoT-based technologies in AAL domain, focusing on how machine learning and intelligent decision making and control are used in IoT based AAL systems, how IoT integration technologies and platforms are employed for AAL solutions, what methodologies and tools are used for multi-agent based intellectual applications for assisted living, how ow cognitive and affective IoT is adopted for IoT based AAL systems, and what are the needs to consider psychosocial factors of human-technology interaction, communication and usage, and how localization, tracking and activity detection technologies are integrated into IoT based AAL systems.  
This survey agrees with the previous surveys [161; 162; 163] in the AAL domain that more inter-disciplinary collaboration, human-oriented studies, and increased standardization is required to achieve more viable AAL implementations while employing the power of the future IoT [164].  
The foreseen impacts of the implementation of IoT for AAL will target three specific societal issues:  
* Digital transformation of public sector by implementing smart and personalized public e-services;
* Improved quality of life, work, leisure conditions and capabilities of the society members through application of innovative personalized intelligent products and services;
* Enhanced security and social isolation prevention.  
The IoT technologies for AAL should also support economic development primarily in the short-to-medium period through tackling the following economic and societal issues:  
* The need to foster knowledge- and technology-based economic development to support ageing population.
* The need to develop new markets for smart devices to diversify and increase sustainability of the digital economy that addresses the needs of active living and ageing.
* The need to encourage private investment in the smart IoT infrastructure for AAL.  
To address and model these needs we have proposed the acceptance model of IoT-based gerontechnologies for the AAL domain, focusing primarily on the older users. The model summarizes the results of the review of the IoT technologies focusing on the acceptance and need of the adoption of IoT for the assistive living domain. Future work will include the validation of the model using a global survey of older people.
