IntroductionIntroduction

Define a smart environment as Able to acquire and apply knowledge about the

environment Can adapt inhabitant's preferences and

requirements to improve their experience

The type of experience that The type of experience that individuals wishindividuals wish

Safety of inhabitants Reduction of cost of maintaining the inhabita

nts Resource optimization(energy or bandwidth) Task automation

The components of a smart The components of a smart environmentenvironment

Perception of the environment is a bottom-up process

Action execution flows top-down

Invisibility and Unawareness Service discovery Interoperability and Heterogeneity Mobility Privacy and security

Location-aware servicesLocation-aware services

Context (location and activity) awareness Current activity state of the user The characteristics of their environment

Mobility and activity creat an uncertainty of their state Minimize this uncertainty as captured by Shann

on’s entropy measure

Mobility / activity trackingMobility / activity tracking

Predict future mobility and actions Reduce the location uncertainty Minimizes the entropy Help device automation and efficient resource

management Single and multiple inhabitant
