IoT Android Gateway for Monitoring and Control a WSN

Precision agriculture and the automation of agricultural processes such as irrigation with the use of current technologies, create the need to develop IoT gateways for WSN with Bluetooth Low Energy motes that demonstrate their functionality through a testbed. The challenge of developing both the testbed and an application for Android smart phones with gateway functionalities to package the sensor data into MQTT messages and send it to remote server or cloud computing and, in turn, be a tool for monitoring on-site of sensors and controlling the actuators present in the mote motivated the development of this work. We carried out tests on the proposed testbed, which denotes its functionality, and shows there is a fast and stable IoT gateway with low CPU and RAM usage, ready for IoT applications such as Precision Agriculture. The application design is extensible to other OS for smart phones and tablets.
