An approach to beacons-based location for AAL systems in broadband communication constrained scenarios

The general objective of this article is to implement an Ambient Assisted Living (AAL) system aimed at monitoring the health state of elderly people in the particular conditions of Ecuador (South America). It is intended that the system contributes to the health state of these people through the monitoring of significant variables of their activity and that of the caregiver, and specific events such as daily activity, falls or location among others. To this end, it is planned to deploy a network of wireless sensors in the home environment that have a high autonomy, in addition to some sensors integrated in a single wearable device, very small and comfortable.In this article we will focus on the evaluation of indoor location by studying the signal strength (RSSI) received from a beacon carried by the user with respect to the central reading nodes. Once the internal location has been set, the reading of other data from additional sensors will allow monitoring adapted to the AAL environment. The key to this work lies in the development of a low-cost system which works in areas that have restricted broadband communication infrastructure typical for the territory of Ecuador, where its application is foreseen for the monitoring of elderly or dependent persons.
