The other day, I re-visted some older papers on how mobile phones and emergency response. I would like to highlight a paper on the WIPER-system that outlines some nice new ideas of how the mobile phone infrastructure could provide new means to better understand an evolving situation.

This paper describes the Wireless Phone-based Emergency Response (WIPER) system. WIPER is designed to provide emergency planners and responders with an integrated system that will help to detect possible emergencies, as well as to suggest and evaluate possible courses of action to deal with the emergency. The system is designed as a distributed system using web services and the service oriented architecture. Components of the system for detecting and mitigating emergency situations can be added and removed from the system as the need arises. WIPER is designed to evaluate potential plans of action using a series of GIS-enabled Agent-Based simulations that are grounded on realtime data from cell phone network providers. The system relies on the DDDAS concept, the interactive use of partial aggregate and detailed realtime data to continuously update the system, which ensures that simulations always present timely and pertinent data. WIPER presents information to users through a web-based interface of several overlaid layers of information, allowing users rich detail and flexibility.

I think your blog seems to be informative.Mobile phones are really useful device.Keep on posting. Waiting for your next post. With regardsEnterprise GISGIS India
Sounds like a good system!For now I use the ImportantNumbers iPhone app that displays my exact GPS position on the dialling screen while calling emergency numbers.
