Agile environmental monitoring is a novel style of environmental-monitoring development that lets you rapidly develop sensor devices and monitoring systems through trial and error during continuous sensing. The authors developed three environmental-monitoring systems and adapted them in situ based on actual field requirements. This article is part of a special ...

For protecting the public health, many research groups have tried to capture dense air quality information using sensorized vehicles that travel within urban areas. However, it remains difficult to accumulate real-time and fine-grained air quality information to fulfill a wide variety of requests from citizens and authorities. In this paper, ...

Conservation of biodiversity is an important issue. We are investigating a system for monitoring the habitat of endangered fish (Japanese rosy bitterling) using a wireless sensor network. Accordingly, measurements are taken for dissolved oxygen (DO), water temperature, air temperature, humidity, and illuminance. In this paper, we describe this habitantmonitoring system ...

This paper describes a spatial-temporal indexing method for moving objects with a technique to predict future motion positions of moving objects. To build efficient index structure, we had an experiment to analyze practical moving objects, such as people walking in a hall. As the result, we found that any moving ...

In recent years, various small sensor nodes have been developed for recognizing real world situations and events for the development of context-aware systems. We consider that the acceleration sensor is one crucial element for recognizing various types of situations because it has rich and simple information. An application system using ...

The Object-Blog service application automatically converts raw sensor data to environment-generated content (EGC), including texts, graphs, and figures. This conversion facilitates data searching and browsing. Generated content can serve several purposes, including memory aids, security, and communication media. In Object-Blog, personified objects automatically post entries to a weblog about sensor ...

The system framework, Tag and Think , proposed here enables us to introduce ubiquitous environments easily and simply by attaching sensor nodes to physical objects without any information about the objects. In the framework, we present a method that uses real-world knowledge constructed from a person's common knowledge to infer ...

We propose a spatial-temporal indexing method for moving objects based on a prediction technique using motion patterns extracted from practical data, such as trajectories of pedestrians. To build an efficient index structure, we conducted an experiment to analyze practical moving objects, such as people walking in a hall. As a ...

In a ubiquitous computing environment, small computers attached to physical objects are required to send sensor data to many other nodes on a narrowband wireless network to provide various types of context-aware services. To reduce the cost of sending sensor data, this paper proposes a notation to indicate a pair ...

Assuming an environment in which a sensor network always collects data produced by sensors attached to physical objects, the demonstration system presented here searches sensor data for corresponding real-world events using a natural language (NL) words in a query. The system translates each query into a physical quantity representation also ...
