Interactive Street Sensing for City Monitoring Systems

Explore the concept of "Alive Street," where people contribute environmental data via cell phones, forming a sensor network for urban monitoring. Learn about similar projects and the ISS solution for small-scale street monitoring systems. Delve into the architecture, implementation plan, and future concerns of this innovative city monitoring approach.

  1. Interactive Street Sensing as basic deployment of city monitoring system Authors: B. Sc. Stanislava Stanković, School of Electrical Engineering, University of Belgrade B. Sc. Marko Stanković, School of Electrical Engineering, University of Belgrade ProSense special section, TELFOR 2008.

  2. Introduction • Life – getting too fast • People – getting mobile • + • City – getting “alive” • Via • Streets – getting able to offer • information • Fun & useful ProSense special section, TELFOR 2008.

  3. Introduction • New approach tocity monitoring • “Alive street” concept • People take part • in the new system • taking from the environment • as much data as they can get • + • People,by using cell phones, • provide the environment • with information • (spontaneous service payment) ProSense special section, TELFOR 2008.

  4. Similar Projects • SensorScope • 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 • CitySense ProSense special section, TELFOR 2008.

  5. 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 IoT ProSense special section, TELFOR 2008.

  6. ISS Solution • Street monitoring • Microcontrollers & Sensors • Video tracking (not precisely) • Different parameters: • temperature • humidity • noise • CO2 • CO (“Silent Killer”) ProSense special section, TELFOR 2008.

  7. Architecture Analysis Server component Nodes Internet IEEE 802.15.4 USB Base station Bluetooth Cell phone ProSense special section, TELFOR 2008.

  8. Architecture Analysis • Present architecture: • Street (covered with leaves ) • + • People, walking and carrying cell phones • Improved architecture: • Microcontrollers equipped with sensors • + • Microcontrollers - Bluetooth enabled ProSense special section, TELFOR 2008.

  9. Implementation plan • Java (Squawk VM) • vs. • NesC (TinyOS) • Server app • Sensor Node app • (Sun SPOTs vs. SHIMMER) • Base station app • Mobile phone app ProSense special section, TELFOR 2008.

  10. Future Concern • More effort is necessary • in order to resolve problems • in system implementation • Present problems and solutions (in case of Sun SPOTs): • Node power supplying (limited battery life) • For now, we have in mind to put SPOTs • on fixed power supply, • by using AC-USB adapters, • for solving the limited battery problem. • Different solution is possible in the future. • Number of sensors on a single node • may be increased in the future. • These issues are money dependent. ProSense special section, TELFOR 2008.

  11. Future Concern • Presence - Equipment purchasing phase • Delivery issues • Time issues • HW implies the necessary SW • (Java vs. NesC) ProSense special section, TELFOR 2008.

  12. Conclusion • ISS system • as basic infrastructure • Small scale WSN • Good enhancement capabilities • (on the city level) • Good adaptation capabilities • for indoor monitoring • (houses, hotels, workplaces) ProSense special section, TELFOR 2008.
