R&D project of Multilayered communications network - For disaster-resilient communications

Learning from lessons of The Great East Japan Earthquake in March 2011, MIC (Ministry of Internal Affairs and Communications) of Japanese Government has initiated many R&D programs in order to establish new communications systems which are robust, resilient, and dependable in case of disaster and emergency. Our joint proposal “Multilayered communications network” by Tohoku University, KDDI R&D Laboratories, KDDI Corporation, and OKI Electric Industry has been accepted by MIC and the R&D project has started this March. The project is being carried out in collaboration with NICT (National Institute of Information and Communications Technology) and YRP (Yokosuka Research Park). This paper gives the concept of “Multilayered communications network” and introduces R&D subjects of the project. Keywords-Disaster-resilient communications
