1 Wireless Sensor Network Research and Application Ning “Martin” Xu

2 Content Introduction Comparison of WSN Projects – Hardware – Software – Highlights Reference

3 Introduction Wireless Sensor Network (WSN) – Spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions at different locations Applications – monitoring space – monitoring things – monitoring the interactions of things with each other and the encompassing space

4 Introduction (cont’d) – Monitoring space Environmental/habitat monitoring,precision agriculture, indoor climate control,surveillance,treaty verification,intelligent alarm – Monitoring things structural monitoring,ecophysiology,condition-based equipment maintenance,medical diagnostics,urban terrain mapping – Monitoring the interactions of things with each other and the encompassing space wildlife habitats, disaster management, emergency response, ubiquitous computing environments, asset tracking, healthcare, and manufacturing process flow

5 Comparison of WSN Projects CodeBlue (Harvard) – ExScal (OSU) – Alarm-Net (UVA) – Opportunistic Pollution Monitor a.k.a Urban Microclimate Monitoring System (BU) –

6 CodeBlue Medical care, emergency/disaster scenario High date rate, reliable communication, and multiple receivers indoor testbed of 30 MicaZ motes, distributed over 3 floors CS BLDG, 1-10 senders, 3 receivers

7 ExScal Detect, track, and classify multiple intruders of different types Protection of pipelines, borders, critical areas 1000+ XSMs and 200+ XSSs deployed over a 1km by 300m opening in a forest in Florida

8 Alarm-Net Assisted-Living and Residential Monitoring Home Health Care, (Large Scale) Assisted Living Facilities seven-room assisted-living residential unit, with a motion sensor on each wall, a PC running the back-end, and a stargate with the AlarmGate application

9 OPM / UMMS Increasing interest in the environment enable localized data monitoring using low- cost sensing individuals to acquire data about local smog (air pollution) conditions

10 Hardware Sensor Nodes / Boards BlueCodeExScalAlarm-NetOPM/UMMS Pulse oximeter ( Mica2 / MicaZ); EKG (Mica2 / MicaZ, Telos); Motion analysis sensor board (Telos); ** Pluto (based on Tmote Sky); MicaZ; ** eXtreme Scale Mote (XSM); ** eXtreme Scale Stargate (XSS); Mica2 MicaZ; Telos Sky; ** SeeMote; Satire body network (MicaZ, MTS310 sensor board); --

15 Hardware (cont’d) Microprocessor Radio BlueCodeExScalAlarm-NetOPM/UMMS TI MSP430Atmel Atmega128L --ColdFire BlueCodeExScalAlarm-NetOPM/UMMS ChipCon CC2420ChipCon CC1000ChipCon CC2420-- 802.11 or GSM

16 Software O.S. and Routing BlueCodeExScalAlarm-NetOPM/UMMS TinyOSLinuxArm-LinuxWildFireMod Publish/subscribe routing layer; Adaptive Demand-Driven Multicast Routing (ADMR); Discovery protocol; Grid routing; Low power listening; Refer to BlueCode --

17 Highlights Pluto: a wearable sensor design (BlueCode) – based on the Tmote Sky design – TI MSP430 microprocessor – ChipCon CC2420 radio – gigaAnt surface-mount antenna (inverted-F used on the Telos) – tiny rechargeable 120 mAh lithium polymer battery – Mini-B USB connector – 100% compatible with Telos


19 Highlights (cont’d) Topology (ExScal) – its networks are the largest ones of either type fielded to date (Dec 2004) – barrier coverage is sufficient – deploy sensors more densely at the boundary of the region than in its interior – detection criteria – XSM & XSS

20 Highlights (cont’d) Atmel ATmega128L microcontroller Chipcon CC1000 radio 4Mbit serial flash memory quad infrared, dual-axis magnetic, and acoustic sensors weatherproof packaging Intel 400 MHz XScale processor(PXA255) 2532W-B IEEE 802.11b card 64 MB SDRAM, 32 MB FLASH type II PCMCIA slot USB port, and 51-pin mote connector; watertight packaging


22 Highlights (cont’d) SeeMote (Alarm-Net) – Color display – Removable data storage (SD/MMC) – Power consumption meter – Compatible with MICAz and MICA2 motes – Small size, lightweight and low power

23 Highlights (cont’d) OPM/UMMS – measure a variety of environmental factors from multiple units, data can also be downloaded for users to make their own calculations (i.e. MATLAB integration). – requires little maintenance: self-powering, hibernate and wakeup mechanism, calibrated sensors can function without replacement for at least two years – allows for many administrative features; combination of the Apache webserver, MySQL database, php code, and python code, high performance data driven applications
