  1. Mobile Personal Agents for Smart Spaces Iván Marsá-Maestre, Miguel A. López, Juan R. Velasco and Andres Navarro ICPS 2006 Lyon, France June 28th, 2006

  2. 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-

  3. SETH SETH: Smart EnvironmenT Hierarchy • 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

  4. SETH SETH: Smart EnvironmenT Hierarchy

  6. SETH SETH Devices • 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

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

  8. Mobile Personal Agents The Personal Agent • Intermediary between the user and the system

  9. Mobile Personal Agents Personal Agent Mobility • 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

  22. Simulations Simulation scenario • 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

  23. Simulations Simulation results

  24. Conclusions Conclusions and future work • 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)
