WSN – Introduction (1) • Wireless Sensor Networks (WSN) • Set of small autonomous devices with solid power capacity • and communication capabilities, • working together to solve different problems • Different topologies Different protocols in use “Horse Shoe” “Fellowship of the Ring” “Out of Order” ProSense @ IJS, December 2008
WSN – Introduction (2) • WSN – Youth and History • Relatively new technology • Intensive R&D during past decade • History begins at UC, Berkley • Smart Dust (project funded by DARPA) • TinyOS R&D progress through time ProSense @ IJS, December 2008
WSN – Introduction (3) • Open Qs in healthcare system of today • Healthcare system is becoming more complex • Healthcare system is becoming more expensive • The world’s population is aging • Number of persons in need of homecare is growing • Number of persons suffering from diseases is growing • Number of medical mistakes is growing • Number of lawsuits is growing ProSense @ IJS, December 2008
WSN – Introduction (4) • WSN – The most powerful “weapon” • of modern healthcare ProSense @ IJS, December 2008
ProSense Project Statement • Belgrade’s mission • Research potential improvement • Wireless sensor network development • (Domain of Health Monitoring Systems) PEARLS Of WISDOM IMPLEMENTATION SOLUTION A N A L Y S I S R E S E A R C H ProSense @ IJS, December 2008
WSN – Existing Medical Applications • Real deployment of WSNs • Existing medical applications (EXMA) • bring new approach to the concept of healthcare ProSense @ IJS, December 2008
EXMA – Important Issues • Engineering issues • (different devices and frequencies, real-time services, • power consumption, reliability, security) • Social issues • (Does the usage of these applications • affects people’s daily lives?) • Patients’ well-being issues • (Technology should only be used to heal, not to harm!) ProSense @ IJS, December 2008
EXMA – Technologies in Use • Great advantage of WSNs is their compatibility • with existing infrastructures • WBAN (Wireless Body Area Network) • WPAN (Wireless Personal Area Network) • Sensor Networks • RFID (Radio Frequency IDentification) • GPRS • Wireless LAN (802.11 standard) WBAN WPAN Sensor Nets RFID GPRS WLAN ProSense @ IJS, December 2008
EXMA – 10+ • CodeBlue & 10Blade & AID-N • SMART • MobiHealth • MyHeart • - WIISARD • - MIThril • - Satire • - UbiMon • - AlarmNet • BikeNet ProSense @ IJS, December 2008
EXMA – Exhaustive Comparison • - Exhaustive comparison among projects • is done in terms of: • Description level • Project’s goals • Hardware platform • Software platform • - Theory based vs. Practice based ProSense @ IJS, December 2008
EXMA – Conclusion ProSense @ IJS, December 2008
Interactive Street Sensing as monitoring framework B. Sc. Stanislava Stanković, School of Electrical Engineering, University of Belgrade E-mail: saska58@gmail.com B.Sc. Student Marko Stanković, School of Electrical Engineering, University of Belgrade E-mail: marko.stankovic@gmail.com ProSense @ IJS, December 2008
ISS – Introduction • Life – getting too fast • People – getting mobile • + • City – getting “alive” • Via • Streets – getting able to offer • information • Fun & useful ProSense @ IJS, December 2008
ISS – Problem Statement • How to deploy • an efficient street monitoring system? • Points to scan: ProSense @ IJS, December 2008
ISS – Similar Existing Solutions • 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 @ IJS, December 2008
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 ProSense @ IJS, December 2008
ISS Architecture Overview Server Nodes Internet USB IEEE 802.15.4 Base station Bluetooth Cell phone ProSense @ IJS, December 2008
ISS Implementation • HW platform: • SunSPOTs or SHIMMER • SW platform: • Java (Squawk VM) or NesC (TinyOS) • Server app • Sensor Node app • - Base station app • Mobile phone app ProSense @ IJS, December 2008
ISS – Future Plans • More effort is necessary • in order to resolve problems • in system implementation • Present problems and solutions • - 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 (solar panels) • Number of sensors on a single node • may be increased in the future ProSense @ IJS, December 2008
ISS - Conclusion • ISS system • as basic infrastructure • Small, but scalable WSN • (on the city level) • Easily adaptable • for indoor monitoring • (houses, hotels, workplaces) ProSense @ IJS, December 2008
