In this paper, a remote monitoring system enabled with the smart internet of things (IoT) station for ambient assisted living (AAL) and smart environments is introduced. IoT station that is based on Waspmote platform to work as an intelligent device for capturing the data and transfers through 3rd Generation (3G) cellular module to the cloud by avoiding redundancy. The complete architecture of the developed ubiquitous monitoring system for AAL is elaborated with the process flow. The video camera sensor board with a presence sensor is connected to the Waspmote to take a snapshot or a video clip when there is any movement in the surrounding. The IoT station with the sensor board have a capability to detect and take picture even in a dark environment. The Waspmote generate message as soon as the motion sensor is triggered and send the image to the storage server using file transfer protocol (FTP) or the file transfer protocol secure (FTPs) over cellular communication. The recent related work is reviewed and discussed to show the advantages of the proposed design. Furthermore, the real testbed experiment presents the efficiency of the cellular IoT based monitoring system.
