Interactive Street Sensing as monitoring framework B. Sc. Stanislava Stanković, School of Electrical Engineering, University of Belgrade E-mail: saska 58@gmail. com B. Sc. Student Marko Stanković, School of Electrical Engineering, University of Belgrade E-mail: marko. stankovic@gmail. com Pro. Sense @ IJS, December 2008
ISS – Introduction • Life – getting too fast • People – getting mobile + • City – getting “alive” Via • Streets – getting able to offer information q Fun & useful Pro. Sense @ IJS, December 2008 16/25
ISS – Problem Statement • How to deploy an efficient street monitoring system? • Points to scan: issues Human effort Remarkable Feasible outcome price Engineering Pro. Sense @ IJS, December 2008 17/25
ISS – Similar Existing Solutions • Sensor. Scope - This system is composed of multiple sensing stations which communicate wirelessly, constituting a sensor network. The sensing stations measure environmental data such as air temperature, humidity, surface temperature, incoming solar radiation, wind speed and direction, precipitation, soil water content, and soil water suction. • Urban Sensing • City. Sense Pro. Sense @ IJS, December 2008 18/25
ISS Solution • Previous projects develop large-scale distributed environmental measurement systems centered on WSNs • ISS app proposes small-scale system installed in the street Main approach: “Problem solving should firstly start at your own yard!” In the future (Internet of Things), street concept moving towards the whole city Pro.
