Connecting WSN to Google fusion tables, a REST database for data storage

摘要

Representational State Transfer (REST) is a web architecture that take the advantage of Hypertext Transfer Protocol (HTTP) to invoke a certain code in the server to do action, either to store, update, delete, or query a value in the server. This kind of implementation are the basis of all Application Program Interface (API) system used by the web application. API provide a tools for creating a software and it reduce the barriers for developing application for the Internet of Things. In this paper we implement a HTTP string at sensor nodes to allow devices in the constrained network to push its data to the targeted server, with the help of gateway to make the request. This paper used ZigBee connectivity in wireless sensor network environment to transfer sensor reading, collected by the sensor node to the smartphone that act as a gateway to make the HTTP request to the targeted server, which is for this paper is to be stored in Google Fusion Tables (GFT) server. The developed system was tested at laboratory and results are encouraging.
