Outline of Final Research Achievements

When parallel and distribution processing is used for wireless network emulation, the results are different in case that each of the receiver nodes independently run the events without synchronizing among these events. In the previous method, the frame has a seed of the random number to be used for an event execution at the receiver terminals within one hop because a frame is broadcasted in its transmission range. In addition, the information needed for the event execution is also previously shared among the receivers in order to get the same result with being generated by the random values. However, the effectiveness of our previous work is limited within one-hop wireless communication. In this study, we extend our previous method to multi-hop wireless network environment with considering a hidden terminal and sharing parameters needed for the synchronized event execution.
