Motivation Present Web: good at describing Conceptual space –“Show me Chinese Restaurants within 5 miles” Eg. yahoo.com Spatial Web: describes both Conceptual & Physical space –“Find the closest Chinese Restaurant with the minimum waiting time” –“Inform me whenever this freeway becomes congested within two miles or less ”

Design Goals Novel information infrastructure to obtain, manage & deliver spatially-constrained data Information resides at the physical location where it is produced Information sources can have unbounded heterogeneity –as simple as embedded sensor devices –as complex as full-scale databases

How Spatial Web differs from Today’s Web All Spatial web pages have a limited physical ‘DataScope’ Links between the Spatial Web pages mirror the relevant structure in the physical space Student Center Werblin Recreation Center ECE Dept Rutgers Golf Course

Architectural components Pervasive Sensor Networks: forming a ‘WebDust’ of information InfoDispensers: –Data aggregation & distribution devices that blanket the physical landscape and act as information-sprinklers –‘Sprinke’ important local information on users as they pass nearby Pervasive Sensor Networks

Spatial Crawling : Potential Application Using space as an index to search for local data Link structure to navigate through physical space Current Prototype ? Rene Motes with Light sensors P D A
