A UAV based Multi-hop D2D Network for Disaster Management

An "Unmanned Aerial Vehicle (UAV)" is used for establishing communication in a Non-Functional Area (NFA) or disaster area where Base Stations (BSs) get damaged. This paper investigates a UAV based cognitive hybrid multi-hop Device to Device (D2D) communication using a clustering technique in a downlink scenario. The UAV can communicate through a multi-hop D2D network to a maximum number of victims. The UAV assisted cognitive hybrid multi-hop D2D network is proposed to improve the Spectrum Efficiency (SE) and Energy Efficiency (EE) in a NFA. The overall outage probability, SE, and EE are investigated for different values of the number of clusters, the distance between two D2D users, the transmit power of D2D users, and the impact of maximum allowable interference power on outage probability is also studied. The impacts of SE and EE are also shown.
