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

Middleware

! 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 nodes

using mobility models

• Constant computation time Jardin des Tuileries

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 “3cixty” and “Sarathi”

• Improving urban mobility, in Europe, and India!
