  1. Live E! Workshop 2006-06-29 @102A1

  2. Introduction • Theme • Content-Based Network (CBN) • Aim • To Learn about Publish Subscribe Model • Introduction to Application Layer Messaging • To Provide Materials concerned about Routing • Work (today) • Construct CBN as a Overlay Network • ScenarioⅠ,Ⅱ,Ⅲ,Ⅳ. • Performance Test (if possible).

  3. Review of CBN • CBN consists of : • Subscriber • registers “Predicates”, which he wants to receive. • Publisher • sends message into CBN. • Router • handles messages from publisher to subscriber, depends on the CONTENT of the message CBN Router Publisher Subscriber

  4. Message in the workshop <?xml version=“1.0” ?> <sensor_data> <sensor_id>92a6e710-fdda-4317-a862-bacb5d53475c</sensor_id> <sensor_type>Temperature</sensor_type> <time>2006-05-12 03:12:34</time> <latitude>35.54256</latitude> <longitude>139.2345</longitude> <value>25.7</value> </sensor_data> sensor_id: Universally Unique IDentifier (UUID) sensor_type: Temperature, Humidity, Pressure, RainFall, WindDir, WindSpeed time: Current Time latitude: [-90 ,+90] (“+” means north, “-” means south) longitude:[-180,+180] (“+” means east, “-” means west) value: depends on sensor_type

  5. Examples of Predicates • All the Message /* • Temperature Message /sensor_data[sensor_type=’Temperature’] • Message of North East of the Earth /sensor_data[latitude>=0 and longitude>=0] All (/*) North East of the Earth Temperature
