PIAX Agent (Agents, Web Services, ) 2. PIAX Overlay (Multi-overlay Handling) 1. PIAX Transport (ID/Locator Separation) Physical Network Structure of PIAX Heterogeneous protocols and devices can be federated Large-scale intelligent services with heterogeneous devices can be realized over wide-area 7

8 Ex.1) Large-scale & Wide-area Data Sharing 1 million peers w/ 100 billion data entries Large-scale Key-value Store (Each node manages a certain region) Discover peers that manage the required area User Terminal Node discovery by Range-key Skip Graph Map area Retrieve locationdependent contents from the matched peers Weather Sensor Map User Movement Histories 8

9 Ex.2) Server-less Watching Service by RFID tags - Mobile terminals with RFID-tag reader collects RFID-tag info and records location - The mobile terminals are connected via PIAX and share RFID-tag information - Observers can search RFID-tag info to estimate the location of target person Mobile terminal w/ RFIDtag reader Family, Staff, Cooperators PIAX peer Collect RFID-tag information RFID-tag Connect & share RFID-tag info by PIAX RFID reader Fixed node RFID-tags around fixed node + RFID-tags read by mobile terminals PIAX peer Observer Observation target Search location by RFID-tag RFID-tag, Location, Time are collected RFID-tag RFID-tag Other Applications Presence Management Notification/Warning Message Delivery Automatic life log etc. 9
