A Web-Based Sensor Data Management System for Distributed Environmental Observation

Takahiro Torii, Yusuke Yokota, and Eiji Okubo
Abstract—Recently, environmental observation gains in importance as primary sensor network application for actual use. To provide a practical environmental observation service, an appropriate mechanism for access and control of distributed sensor data and sensor networks is required. We propose a new web-based sensor data management system that extends the existing typical Sensor Web architecture for distributed environmental observation. Our system connects the Internet and remote places for environmental observation with networks that have relatively narrow bandwidth, such as cell-phone lines or satellite connections. It manages distributed sensor data in remote places and controls traffics between the Internet and remote places properly to provide practical utility to users of applications. We optimize our system for gathering requested sensor data on narrow bandwidth network. It allows users to gather sensor data on demand. Therefore users can obtain necessary and sufficient sensor data. On the other hand, it may fail when additional traffic occurs because of bandwidth restrictions. Consequently we introduce a query management mechanism for prevention of communication faults. We confirm this system can provide necessary and sufficient sensor data for multiple users through the simulation that estimates an appropriate network bandwidth to transfer sensor data from remote places.

Index Terms—Sensor Web, sensor network, distributed data management, query processing, environmental observation
