Flexible aerial relay nodes for communication recovery and D2D relaying

Current mobile communication infrastructure may fail in cases where low coverage areas suddenly become overcrowded by mobile devices or in natural disasters. In this paper, we propose the use of flexible aerial relay (FAR) nodes for communication recovery and device-to-device (D2D) relaying, as an energy efficient and cost-effective way to resolve these issues rapidly. We discuss the technical characteristics of the system and determine analytically the range of the FAR nodes.
