| Research Abstract |
We have proposed construction methods of geographical networks based on recursive divisions of faces or link survivals, in which positions of nodes as base-stations are adaptive to scalably increasing request on future wide-area communication according to population. From theoretical analyses and computer simulations, we show that the proposed network models are efficient in the decentralized routings on short paths and robust in the connectivity against node removals of random failures and intentional attacks. In addition, we find several strategies to avoid traffic congestion and to improve the robustness by adding shortcuts.
