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 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.
