Quoi de Neuf?* Leveraging Things and People as Sensors for Smart CitiesAnimesh PathakProject-team MiMoveInria Paris-RocquencourtBIS 2014

* ’ssup?

The Internet of Things (IoT)

• Connecting the physical world with the virtual world• Leveraging sensing and actuation capabilities embedded in

Things

• Increasing number of mobile Things with many

benefits => mobile IoT

Mobile IoT: Illustrating scenario

Wind-chill in Paris?

How to measure wind-chill?

How to know they are in Paris?

Wind-chill sensor?

Location sensor?

? ?

! So many devices! Diverse types! Unknown availability! Incomplete measurements

Service Oriented

! Coarse grained data

Focus: - On-demand- Discrete- Sensing/actuating requests

Key Challenges of the Mobile IoT

• Heterogeneity (Representation)• Different Things, different data types

• Ultra Large Numbers• Millions of Things, large volumes of data

• Dynamic Environment • Mobile Things, short-life span

More likely to not register

Enough coverage

Design Rationale- Do not register redundant

Things to reduce number- Set coverage threshold

Managing Scale: Probabilistic Registration

Centralized Approach• Compute decision at

registry as search problem• Using global displacement knowledge• But computation time

increases linearly

5

Decentralized Approach• Compute decision on Thing• Estimate displacements

of registered nodesusing mobility models

• Constant computation timeJardin des Tuileries

Scenario

A football match just ended and the train station is crowded. Charlie is going to Alice’s place with his son and he does not want to catch the Metro 7 if it is crowded.

Recognition and Future Directions

• Awarded the “Prix Mashup” (€2500) at the RATP OpenDataLab in

May 2013• Led to appearance on TVFIL78 evening programming

• Federated Social Networking• Privacy policies for mobile social networks

• Incentive Mechanisms• How to encourage people to share their inputs

• Project “Sarathi”, and Inria Lab CityLab (http://citylab.inria.fr)• Tackling smart-city challenges in Europe, India, and the Silicon Valley!
