Abstract

We design and implement a web service for LiteOS-based wireless sensor networks (WSNs). LiteOS is a newly developed operating system for the sensor networks. Taking advantage of UNIX-like shell commands and C programming language supported by LiteOS, we implement a web service middleware which interacts with the front-end web application as well as the WSNs such that users can remotely request and view the sensor readings. Our web service system is equipped with secure membership, a visualizer for sensor readings, and accepts parameterized queries from multiple users simultaneously. We also address the issues of improving user perceived response time and energy efficiency of sensor nodes in the web service.
