| Research Abstract |
In this research, we investigated the theoretical property of data gathering by the store-carry-forward routing and designed an algorithm for efficient data transfer controls in delay tolerant networks. We proposed a mathematical model with random walks to show theoretically the conditions that efficient data gathering is possible by the epidemic routing in real environments. By using this theoretical result, we also proposed an algorithm to control the data transfer efficiently and finally confirmed the validity of the algorithm by theoretical analyses and numerical experiments.
