Summary of Case Studies • We conducted seven case studies with our MDD process Q1:Can we model the application logic in the DataflowML? Q2. Can we model all design decisions related to the tuning of the data quality in our DSMLs? O K N G O K N G IPSN 2013 Ph.D. Forum Application logics of periodic WSN applications Application logics of event-based applications Designs of the applications (communications & task assignments) Designs for tuning related to OS-level functions We could model realistic monitoring WSN applications from the aspect of application designer with our MDD by using multiple abstraction level 18
