ABSTRACT
The demand for continuous data from smart devices is rising day by day, and the massive production of data from mobile users has put a huge workload on pre-existing systems, such as infrastructure-based cellular networks for real-time applications. A major concern is the failure and inefficiency of pre-existing networks to tackle a vast number of traffic requirements, which leads to latency in critical applications such as disaster relief, rescue operations, tsunamis, border security, pandemic control, and many more. UAVs are mostly used to satisfy both customer demands and facilities. Apart from this, advancement in technologies aims to shape the world in a much better way. This paper provides a survey on UAV-based fog computing, i.e., the collaboration of UAVs and fog computing together. Fog computing is basically internet-based computing in which the pool of resources is shared without any direct active management by the user. UAV-based fog computing can have many advantages in terms of infinite demand capability, storage, low latency, data processing, mobility, scalability, etc. In UAV-based fog computing network, security is a big concern. To provide secure communication we considered quantum cryptography and quantum key distribution. This paper also highlights the insights of advantages and challenges of the UAV-based fog computing network.
