主 题：emergency communication UAV coverage connectivity communication network
摘 要：Nowadays,daily human life is closely intertwined with various *** natural disasters or malicious attacks break out,the failure of communication infrastructure due to direct destruction or indirect impact tends to cause a massive outage of *** communication networks play a significant role in rescue ***,a flexible and efficient solution has been provided for emergency communications using unmanned aerial vehicles(UAVs).By means of their excellent characteristics,UAVs,serving as aerial base stations(ABSs),can be rapidly deployed to temporarily rebuild a damaged communication network to restore the users’*** this study,we investigate the use of UAVs as ABSs for an emergency communication scene where user equipment is unevenly distributed and the communication infrastructure has completely failed due to a severe *** communication probability(ECP),which integrates throughput coverage and connectivity,is used to evaluate the performance of a communication *** simulations,we analyze communication improvements that can be obtained by the flexible deployment of *** results show a noticeable increase in ECP when some ABSs are deployed in optimal locations.
