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
4
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!
