Browsing Reality With Sensor Networks
Roland Piquepaille writes "Welcome to the world of 'Reality Mining'! The billions of networked sensors that exist today are generating humongous streams of data. What about 'data mining' this big flow of data and discover our environment in a way that never existed before? Suddenly, sensors would look like pixels and we would start to browse reality as easily as we browse web pages today. Fascinating concept! Some fellows at Accenture Technology Labs are thinking about this and they already have designed some demos of reality mining software. Their demos include web agents, data modeling, GIS systems and much more. They also show how you could detect fires or how you would do virtual shopping. Please read their long article or this shorter summary for a couple of examples." -
Moving Sensor Data Onto The Internet With SensorML
Roland Piquepaille writes "According to this Sensors article, a new XML encoding scheme may make it possible for you to remotely discover, access, and use real-time data obtained directly from Web-resident sensors, instruments, and imaging devices. By describing sensors using SensorML, anyone can put sensors or sensor data online for others to find and use. And because it's XML-based, it means all this data will easily be searchable. "For example, searching for particular kinds of sensors and data in a particular geographic region, with data collected within a particular time window, will be easy. This has significance for science, environmental monitoring, transportation management, public safety, disaster management, utilities operations, industrial controls, facilities management, and many other activities." In this column, you'll find a summary of the Sensors' story which contains more technical details about the technology. And if you're really interested, please visit the SensorML homepage." -
Wireless Mesh Networks
Roland Piquepaille writes "Robert Poor is CTO of Ember Corporation. He contends that point-to-point or point-to-multipoint networks typical of industrial wireless communications systems have limited scalability and reliability. 'In contrast, wireless mesh networks are multihop systems in which devices assist each other in transmitting packets through the network, especially in adverse conditions. You can drop these ad-hoc networks into place with minimal preparation, and they provide a reliable, flexible system that can be extended to thousands of devices.' The article is pretty technical and contains several illustrations and a case study about the deployment of a wireless mesh network in a water treatment plant. Check this column for Poor's conclusions or read this Sensors article if you have more time."
