Title2• ISS – Introduction• ISS – Problem Statement• ISS – Similar Existing Solutions• ISS Solution• ISS Architecture Overview• ISS Implementation•ISS – Future Plans • ISS – Conclusion• Virtual Sun SPOTs in action


• 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

WSN – Introduction (1)

“Fellowship of the Ring” “Out of Order”


“Horse Shoe”

4/25

• 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





• Open Qs in healthcare system of today

6/25



• WSN – The most powerful “weapon” of modern healthcare

7/25


ProSense Project Statement • Belgrade’s mission Research potential improvement Wireless sensor network development (Domain of Health Monitoring Systems)

8/25


WSN – Existing Medical Applications

• Real deployment of WSNs • Existing medical applications (EXMA) bring new approach to the concept of healthcare

9/25


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!)

10/25


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)

EXMA – 10+

- CodeBlue & 10Blade & AID-N- SMART- MobiHealth- MyHeart- WIISARD- MIThril- Satire - UbiMon- AlarmNet- BikeNet

12/25


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

ISS – Introduction • Life – getting too fast• People – getting mobile +• City – getting “alive” Via• Streets – getting able to offer

information

Fun & useful

ISS – Problem Statement • How to deploy an efficient street monitoring system?

• Points to scan:

17/25


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

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

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

21/25


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

22/25


ISS - Conclusion

• ISS system as basic infrastructure

• Small, but scalable WSN (on the city level)

• Easily adaptable for indoor monitoring (houses, hotels, workplaces)
