Outline of Final Research Achievements

We have proposed two novel control methods that efficiently reduce congestion situation. The proposed methods are based on the mechanisms that virtually conduct congestion information in parallel with message-packets. Both methods show outstanding performance in reducing congestion situation and, thus, enhance the network performance. Furthermore, we have also introduced the cellular automata principle into large-scale network simulation, which is suitable with GPGPU environment and the resulting simulator allows us to simulate upto 1 million nodes within practical time.
