one.world: system architecture for ubiquitous computing
Evaluation: Hypermedia guide for Costa Aquarium Exploratorium Evaluation of Ubiquitous Computing Systems
Pervasive Computing Development & Evaluation-3
Proem http://wearables.cs.uoregon.edu/proem A P2P platform for mobile ad-hoc networks Four entity types: peer (device), individual (us
er), data space, community (a set of entities) Four protocols: transport (XML messages), pre
sence, data, community Application environment: runtime (peerlets &
peerlet engines), peerlet development kits
Pervasive Computing Development & Evaluation-4
Proem Application Environment
Pervasive Computing Development & Evaluation-5
one.world http://one.cs.washington.edu A system architecture for pervasive computing
Provides an integrated and comprehensive framework for building pervasive applications
Includes a set of services, such as service discovery, checkpointing, and migration that help to structure applications and cope with constant change
one.world slides and sample code
