A real time environmental monitoring for smart city surveillance based GUI on Android platform

In our smart city project, citizens can use smart phones, tablet personal computers, and other modern mobile devices operated under the Android Operating System and benefit smart city´s services. Some related works make an emphasis on sensing and delivering of alert message to the user over the wireless sensors networks. Instead, in this paper, we propose a real time environmental monitoring system which aims at quick pollutants detection and sending value immediately to the supervisor. Each value is processed by the supervisor server and compared to a previously defined threshold. In the normal case, the sensed data will be sent to android terminal and when the pollution threshold is exceeded, the user is notified by receiving an alert message on its mobile device. The experimental results demonstrate the efficacity of our project in terms of fast detection, real time response and the capacity to notify user everywhere.
