Abstract
AbstractIn some emergency scenarios, UAV relay network is often used to provide temporary communications services. Different from the absolute position information, this paper proposes a deployment scheme of UAV network which is based on the relative position information. As a dynamic scheme, it contains several strategies for the deployment, retrieval, and topology control. Compared with other two schemes based on the absolute position information, greedy-based scheme and genetic algorithm-based scheme, the network based on our scheme achieves 90% and 70% of the coverage performance of them respectively and significantly outperforms those two static schemes in robustness and load balancing.KeywordsUAVRelay networkDeploymentRelative positioning
