Street CORNERS: Real-time Contextual Representation of Sensor Network Data for Environmental Trend Identification

Abstract-Sensor networks have been deployed for a range of rural and environmental applications. Wellregarded for the volume and range of data which can be obtained, wireless sensor network applications capable of using the data gathered have not been fully realized, particularly in urban settings. Street CORNERS is a wireless sensor network application which supports the contextual presentation of data gathered from an urban setting. The Street CORNERS application offers realtime data display, and provides support for predictive algorithms suitable for anticipating, detecting, and defending urban communities, among others, from environmental threats such as declining air quality and urban flash floods. Street CORNERS is presented in two parts. The network design and deployment is outlined, followed by a discussion of the design of the network application, which is involved in data preprocessing and the contextual presentation of the data gathered for trend identification

A green wireless sensor network for environmental monitoring and risk identification

A sensor-based community network for environmental data gathering and predictive analysis has been developed. A mesh network of wireless sensors reports data to a central site for environmental monitoring and risk identification. Data analysis and visual presentation is provided in a geographical and temporal context. This network is considered green due to decreased energy usage by the overall network as well as its actual application, which permits environmental information to be contextually presented and communicated with concerned urban community as well as decision makers. Periodic data reporting from the sensor network, in contrast with the usual timestamp synchronisation, reduces the amount of communication required between network nodes, resulting in an overall energy saving, while not compromising the nature of the data gathered. The sensor network applications provide an outstanding representation of green networking as sparse but sufficient environmental monitoring, accompanied by real-time data analysis, and historical pattern identification permits risk identification in support of public safety and protection. © 2011 Inderscience Enterprises Ltd

Real-time environmental monitoring and notification for public safety

The design of a wireless sensor network database that records the data reported by distributed sensors and implement support for queries and data presentation is discussed. The chart software permits a sensor query to report the specific details of that sensor at one point in time and present the sensor status for prior dates and times. The bar chart display of real-time sensor data, with appropriate date and timestamps, provides an opportunity to analyze new patterns or correlations, which can then be followed appropriately. The WiNS project demonstrates the viability of a wireless sensor network for real-time monitoring and reporting and the utility of the system for health care and sustainability enable to construct some of the correlation patterns presented from the data. The ability to present the geographical location of a node, along with near real-time interactive sensor data can provide significant contextual information for the data gathered by the sensor network
