1 SensorPlanet: a global test platform for mobilecentric wireless sensor network research Owner: Contacts: Henry Tirri Barbara Heikkinen, Boda Péter Nokia SensorPlanet Nokia Research Center, Helsinki

2 Why a phone should play any role in Wireless Sensory Nets?... because it is there Nokia SensorPlanet

3 SensorPlanet a Nokia-initiated global cooperation on large scale wireless sensory networks mobile phone oriented sensory input acquisition a research platform that enables collection and analysis of sensory data on a never seen quantity Nokia SensorPlanet

4 SensorPlanet in a snapshot Mobile phones act as sensor node and/or sink node. Sink node Application #2 Novel use cases Application #1 Green phones providing environmental data, sharing Sink node Central Central Data Data Repository Service manifolds Traffic, masses of people... the more data shared the more accurate Mixed sensor networks which consists of ordinary sensors and mobile sensors Nokia SensorPlanet ( Copyright 2006 Petri Koskelainen) ( Copyright 2000 Martin Lamm) Urban games Locations shared, participation of the public...

5 SensorPlanet University Cooperation Ultimate goal to have multiple SensorPlanet sites around the globe Data gathered on sites accumulated in central repository Common access to accumulated data for research purposes Single interface to sensory data from the world Universities: MIT/CSAIL (CarTel) and Media Lab UCLA: Urban Sensing NYU: urban games & body-area networks, physical diary Stanford University of Washington: in-door positioning, orientation sensing Cambridge University: pollution detection others under negotiation Nokia SensorPlanet

8 Virtual Graffiti Description: Users movement is tracked and they can leave virtual tags in their indoor environment. These tags can include picture, music, video or text, so they are a sort of virtual graffiti. Other users can view existing tags and leave their own. Objective: Implement a client-server architecture for Virtual Graffiti with tag storage and client location tracking Nokia SensorPlanet

14 Why should we be interested here in Nokia? wireless sensor networks are one of the major developments in the evolution of Internet ubicomp will be there after a very slow start we want to be part of this... because it is cool 2006 Nokia SensorPlanet

15 Where can we use our research - applications? Environmental Monitoring, Conservation biology,... Precision agriculture, land conservation,... built environment comfort & efficiency... alarms, security, surveillance, treaty verification... Civil Engineering: structures response condition-based maintenance disaster management urban terrain mapping & monitoring Ubiquitous computing context aware computing, non-verbal communication Intelligent traffic & logistics Wellness and health-care Integrated robotics By courtesy of CENS.ucla.edu Nokia SensorPlanet

18 Prototype Device Implementation Wireless Motion Band Wireless Motion Bands are designed for comfortable wear in different body parts to enrich user experience in gaming. Wireless Motion Bands allow the use of (full) body motion tracking in gaming: Direct 3D body motion control of a gaming character Detection of body poses & gestures Local multi player gaming. Low-latency multi device Bluetooth connectivity. Interoperability with Wireless Game Pads. Design by Mikko Aarras, Nokia Design By Courtesy of Jukka Salminen Nokia SensorPlanet

19 User Interaction Examples Virtual Snowboarding Direct body motion control of a computer character Body poses Balance Direction Speed Jumps Landings Nokia SensorPlanet

20 There is always a need of an ecosystem... Portfolio of communication and monitoring devices IR, Bluetooth, RFID, USB Mobile device as intelligent hub and portable application platform Operator traffic PC and server applications and hosted internet services Server - Service providers - Peer community PC -Coach - Trainer -Doctor -Nurse - Caregiver - Operator DB Some sensors may be embedded in terminal Internet services Nokia SensorPlanet

21 Virtual Graffiti Visualisation Virtual Graffiti develops a horizontal platform for indoor tag placing Positions are determined by Bluetooth beacons User can leave/read out/modify/etc. virtual objects left to physical places within the NRC/Toijala premises The current visualisation: Violet balls represent Bluetooth beacons and the red ones at the centre of the picture represent clients. The red balls that constitute an oval represent other Bluetooth devices that the beacons have found. The thickness of the lines represents the frequency of scans made between the client and a Bluetooth device. On the top of the visualisation box the five last events are displayed Nokia SensorPlanet

22 2006 Nokia SensorPlanet Some research challenges

23 Some key technological challenges Sensor data challenge : how to make the high-volume sensor data useful query/search problem data management problem Mobile adaptation challenge : self-configuration and adaptation Integration challenge : how to integrate (two-way) WSN to Internet based services (create the gateways ) Power challenge : even high-power mobile nodes are not enough User interaction challenge : how end-users will benefit, interact Nokia SensorPlanet

24 What sort of raw (context) data management problem we are facing? a multidimensional (2-30) vector of real values frequency 0.5s - 1 day typically always-on a 1-4M pixel image frequency 10 min - week(s) very irregular, high-intensity bursts (many images within minutes) a 100K-1M sound file frequency 1 min - days irregular; streaming Naturally many application domains require a mixture of these 10K phones - vector every 2 min results in 2.7 (US) billion vectors/year 200M phones - vector every 60 min results in about vectors/year Nokia SensorPlanet
