    • PSC-Oulu objectives
      2/3/2010
      PSC presentation@Motive workshop, Espoo
      To research and develop a pervasive service computing model and a description language
      To research and develop a service collaboration framework to strengthen the capability of collaboration in a pervasive computing environment
      To research and develop a service coordination framework to strengthen the capability of coordination in a pervasive computing environment
    • Conceptualization –service collaboration and coordination

      • Four solutions for automating a generic user activity
      • Solution 1: Seek a service composition consisting of a set of services within one party for achieving the travel reservation goal.
      • Solution 2: Seek an optimal service composition consisting of a set of services within one party for achieving the travel reservation goal taking into account constrains of service properties of cost, time, etc
      • Solution 3: Seek a service composition consisting of a set of services among multiple partiesfor achieving the travel reservation goal
      • Solution 4: Seek an optimal service composition consisting of a set of services among multiple parties for achieving the travel reservation goal taking into account constrains of service properties of cost, time, etc
