A Geographic Information System framework for the dataset visualization in Wireless Sensor Networks
Abstract
In Wireless Sensor Networks (WSNs), collecting data from sensor nodes and analyzing them is a challenging task. A Geographic Information System (GIS) could be a better way to analyze, manage, and represent the dataset collected by sensor nodes. Motivated by these considerations, we proposed a system to visualize the WSN dataset in real time using a software implementation of the GIS framework called ArcGIS. In this research, we have implemented our proposed system where a couple of sensor nodes has been deployed to collect Dissolved Oxygen (DO) and water pH value continuously from the John Gray Center pond of Lamar University. To keep track of each sensor node we have accumulated their precise location, sensing time, and corresponding data in our lab. After analyzing couple of data storing technique, we have decided to use PostGIS (a geospatial database) to store data and developed an ArcGIS centric application. Finally, with the help of that application, a web map was designed combining all different data source layers for end users where all the technical details have been encapsulated behind a base map. This web map has been hosted in a web server so that users sitting in any location can easily access and visualize desired data with a real time update. This research work has been supported by National Science Foundation under Grants CNS-0922888 and CNS-1427838.
