2 How big is the Internet? billion Internet users 40 % of the world s population Exabytes of traffic per day 600 million websites billion Internet users ~ 60 % of the world s population Zetabytes of traffic per day IoT: 30 billion connected devices Predictions by Cisco, Ericsson & other statistics organizations - 2

3 Crowd & sensing - 3

4 Crowd- sensing kraʊdːsɛnsɪŋ Capability of li,ing a (large) diffuse group of par7cipants to delegate the task of retrieving trustable data from the field. This includes: Par6cipatory sensing involves the user in the sensing task (eg. surveys) Opportunis6c sensing uses mobile sensors carried by the user (eg. smartphones) See also: Ambient compu<ng, mobile crowdsourcing - 4

10 How does it work? - 10

11 How does it work? A crowd sensing API (JavaScript) Example of crowd sensing app - 11

12 How does it work? Privacy & Energy - 12

13 How does it work? Privacy & Energy - 13

14 APISENSE & PRACTIC (PRAtiques CulTurelles et usages de l Informatique Connectée) sensors oriented towards the environment... and towards the smartphone itself - 14

15 MetroScope: a multidisciplinary structure for the scientific Observation of the Internet Partenaires Inria (Madynes, Spyrals, Diana, Muse) RENATER AFNIC Université de Caen ENS / ENSSIB IMT Grenouille ip-label LIP6 Consortium o Initiative by Inria of a consortium in 2012 Metroscope ( o Main partners: Inria, Université de Caen, AFNIC, RENATER, ARCEP, IMT, ENS/ENSSIB Objectives o Internet Observatory: create a large scale national observation platform o Computer Science: research new architectures/protocols to overcome current limitations/faults, propose future improvements o Social Science (SHS): Internet usages, cartography, influence on the society -

16 PRACTIC & APISENSE First project under Metroscope consortium Goal o Study the influence of mobile technologies on the society Approach o Deploy crowd-sensing campaigns (using APISENSE ) -

17 Deployment of PRACTIC into APISENSE Campaign design Composit method digital methods (crowd-sensing) digitized methods (online survey) qualitative methods (interviews) Possibility of anonymous contacts Script updates or requests for interviews Time-stamped measures (no content) screen activation network detection and performance calls / SMS applications battery device model and static measurements Self-administered questionnaire (138Q) sociodemographics equipment / configuration cultural practices advertisment and privacy - 17

18 Deployment of PRACTIC into APISENSE Dissemination of the application Privacy Statement (privacy) + Display of personal data (incentive) - 18

20 Data collection "in the wild" - 20

21 Technical determinations of uses Battery limits, network performance, screen size, software stability... are constraints that define our relation to the Internet - 21

22 Observing the rhythms of lifestyle from smartphones social embeddedness of the uses and technical organization of society - 22

23 Does metrology produce a "truer truth" in sociology? Comparison of questionnaire and measurement on 4 simple questions - 23

24 Work in progress Collaborating with scientists... Mobility analysis (CEREMA, Microsoft) Climate monitoring (ULCO) Internet observatory (MetroScope) - 24
