A Resilience Management Architecture for Communication on Portable Assisted Living

Abstract

The Internet of Health Things interconnects wearable and portable devices, supporting critical healthcare applications such as Ambient Assisted Living (AAL) that retrieve crucial information from users (e.g., vital signs, activity tracking, fall detection) towards smart medicine. However, existing assisted living systems cover a pre-established area, limiting users to small spaces and constraining daily activities. These systems have restricted requirements in terms of latency and availability, compelling to fast advances in network infrastructure and essential services as sensing, connectivity, and end-to-end communication. This article presents a novel resilience management architecture for communication on portable assisted living, considering that IoHT devices have access to multiple access networks, such as fixed and mobile, and the concurrent use of those networks, extending the communication range and managing communication resilience. Based on the architecture, this work details a Portable Assisted Living System and its performance evaluation, achieving low delay and high throughput as well as increasing communication resilience.
