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?
Service
?
Oriented
! Coarse grained data
Middleware
Focus:
- On-demand
- Discrete
- Sensing/actuating requests
! So many devices
! Diverse types
! Unknown availability
! Incomplete

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

Managing Scale: Probabilistic Registration
Design Rationale
- Do not register redundant
Things to reduce number
- Set coverage threshold
✔
Jardin des Tuileries
Enough
coverage Centralized Approach
More likely•to Compute decision at
not register registry as search problem
• Using global displacement
knowledge
• But computation time
increases linearly
Decentralized Approach
• Compute decision on Thing
• Estimate displacements
of registered nodes
using mobility models
• Constant computation time

Managing Scale: Probabilistic Look-up
Candidate Thing
Selected Thing

Probabilistic Look-up:
Normal distribution
Dmax

X1
r2
r3
Candidate Thing
Selected Thing
r4
Lookup controls participation of Things
