On Developing a Novel Versatile Framework for Heterogeneous Home Monitoring WSN networks

Abstract

The ability to deploy efficient and versatile WSN networks in the home environment is and will remain in the years to come a cornerstone objective in wireless networking. Respective services are continuously expanding requiring novel design and implementation approaches able to cover all relative present and even more importantly future requirements. This paper aims to present and convey knowledge and experience gained from such an effort in the context of home monitoring. Respective discussion covers all relative aspects and analyzes all critical challenges addressed ranging from identification and specification of the main requirements, to possible implementation approaches considered and finally the actual development undertaken. The final outcome considering the WSN home monitoring infrastructure as well as extracted knowledge and practical conclusions can be proven useful for further extending such an endeavour or even pursuing a different approach.

On the Design of Low-Cost IoT Sensor Node for e-Health Environments

“…The Mean Square Error (MSE), the Normalized MSE (NMSE) and the Signal to Noise Ratio (SNR) parameters were mainly used for comparison. The aforementioned parameters are defined for a reference signal v ref of N samples and a real signal v according to Equations ( 14) and (15).…”

“…The GW can be programmed to separate the sensor values of different data files. Although the proposed communication protocol does not support the interoperability or extendibility of a digital sensor network like the one presented in [15], it can nevertheless handle analog sensors in a versatile way in the sense of supporting almost any sampling profile. Future work will incorporate a Message Queuing Telemetry Transport (MQTT) protocol to transmit data over a broker to the user so as to scale the architecture towards the support of multiple users [34].…”

“…As a result, meaningful information about patients' symptoms is provided immediately, facilitating their treatment and remote monitoring in real-time [3,4]. A significant advantage is that it is possible to monitor patients from home via wireless sensors, thus reducing the need for regular hospital visits [5]. Furthermore, these medical devices can send alerts if something serious happens [6][7][8].…”
