Computer Engineering Electrical Engineering Engineering Experiments event-triggered design networked embedded automation systems time-triggered TinyOS sensors actuators component oriented Systems that interact with the physical world can be designed in either an event-triggered (ET) paradigm or a time-triggered (TT) paradigm. Most real-time systemstoday are designed in the TT-paradigm because it is easier to achieve predictableperformance. However, when some critical aspect of the system changes, designsbased on the TT-paradigm must be completely revised. Modern application requiresystems to be flexible and reliable. Since the event-triggered systems are fundamen-tally designed as a colletion of loosely coupled local entities, it was interesting toinvestigate the predictablity of ET-systems. This investigation focused on a ET-design for operating a MicroFactory,which is a physical simulation of a discrete assembly system. The design was im-plemented and evaluated using a collection of networked embedded microcontrollers.Common tasks in a discrete assembly environment were captured as a collection ofprimitives. These primitives were redesigned and implemented in the ET-paradigm.Experimental results collected reflect the performance at the level of a single nodeand at the level of the system. Results were studied in comparison with similar onesobtained using a design that was based on the TT-paradigm. In the future, principlesand techniques for reconfigurability can be incorporated in the proposed framework. 2010-12-16 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1291754351 http://rave.ohiolink.edu/etdc/view?acc_num=akron1291754351 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
