Smart Environments
Smart Environments

• Acquire and apply knowledge about their
  inhabitants and their surroundings in order to
  adapt to them
• Goals generally, comfort and efficiency
• Adapt the environment to suit user preferences
• Reduce the effort needed to perform routine tasks
• Adequate resource management ecology-

SETH Smart EnvironmenT Hierarchy
SETH

• A Hierarchy of Smart Spaces
• Self-contained locations within the environment
• Characterized by a set of devices DA, a set of
  services SA, and a given context CA
• May be hierarchically arranged
• Aggregation and inheritance rules for devices,
  services and context

SETH Devices
SETH

• Smart Space Agent Platform (SSAP)
• Agent Platform
• High-level agents
• Agents controlling simple devices
• Devices without Agents
• Devices with Agents
• Autonomous sensors/effectors
• Identification Devices
• Personal devices

SETH Software Agents
SETH

• Smart Space Coordination Agent (SSCA)
• Device, agent and service management and
  discovery
• Device agents
• System Agents (including Context Agents)
• Service Agents
• Personal Agents (PA)

The Personal Agent
Mobile Personal Agents

• Intermediary between the user and the system

Personal Agent Mobility
Mobile Personal Agents

• Intermediary between the user and the system
• Needs to be contacted at every user request
• User mobility ? Inter-platform communication
  increases
• Solution personal agents are mobile
• Mobile personal agents
• Associated to a Home Agent Platform (HAP)
• Clones and moves when the user requests a service
  on another SSAP
• When user leaves a SSAP moves to the ancestor
  SSAP
• Possible problem overload of top-level SSAPs
• If the destination node is an ancestor of the
  HAP, it returns to the HAP

Simulation scenario
Simulations

• Example hierarchy tree
• 10 Mbps Ethernet links in workplace buildings
• 50 Mbps WAN at city level
• ADSL (2Mbps downlink, 512 kbps uplink) for user
  residences

Conclusions and future work
Conclusions

• Hierarchical approach to service personalization
  in smart environments using mobile agents
• Hierarchy ? flexibility and scalability
• Mobile agents ? handle user mobility in an
  efficient way and without relying on personal
  devices
• Open issues
• New smart services
• Adaptive mobility models
• Security layer (specially mobile agent security)
