Towards Safety, Security and Reliability of Data Communication in IoT AAL Applications
Internet of Things (IoT) Ambient Assisted Living (AAL) systems are expected to enable the next generation healthcare, in the era of increased number of elderly and disabled people. IoT AAL is assumed to enable healthcare in the comfort of patients’ own homes, and keep the cost of the healthcare within economically acceptable range. In this paper, we focus on a health monitoring system consisting of a number of sensing devices, cloud services, remote hospital offices connected via communication infrastructure (e.g., WiFi, cellular networks, etc.) aiming at providing safe, secure, reliable and time-efficient services. We identify challenges related to guaranteeing these properties and provide a brief description of our approach that enables reasoning about reliable and time-efficient communication, and outline an approach for risk analysis of safety and security properties.
