Easy implementation of sensing systems for smart living

Abstract

Nowadays system architectures based on Internet of Things (IoT) are becoming a pervasive topic in several applications. Smartphones integrate a growing number of high quality sensors and often they are used as gateways for external sensors, wearable sensors or sensors for ambient assisted living. Several recent projects about smart cities and smart living are experiencing sensory data management by means of smartphones, resulting in large data flow and battery power concerns. In these architectures, using sensors embedded within the smartphone is trivial, and several reliable Applications (APPs) are available; on the contrary, APPs managing external sensors have high Source Line Of Code (SLOC), especially if sensors of different vendors are considered and if the APPs need a high level of personalization. In this work, a solution to easily develop Android APPs handling remote sensors, even of different type and manufacturers, is employed in the context of a smart living application. The proposed approach is based on a framework that allows achieving an easy development system architecture, exploiting the Bluetooth 4.0-4.1 technologies. First implementations focused on safety in a Smart City projects are discussed.
