Investigating the Run Time Behavior of Distributed Applications by Using Tiny Java Virtual Machines with Wireless Communications

From the viewpoint of programming education, distributed application programs carried out in a small JAVA machine group were considered. These computers are equipped with radio communication facility, multi-thread function, LEDs and various sensors. Parallel genetic algorithms and distributed search problems were targeted for the study here. About the latter, a detailed implementation method and the result of the experiment are shown. In such a computing environment, it was understood that the internal behavior and the data communication in the distributed application were easy to be grasped by an effect of visualizing them by the physical interface.
