Survivable free space optical mesh network using high-altitude platforms

Free space optical (FSO) communication refers to the information transmission technology based on propagation of signals in space. FSO requires that transmitter and receiver directly see each other. High-altitude platforms (HAPs) have been proposed for carrying transceivers stratosphere. A multihop HAP network with links can relay traffic between ground nodes. In this study, we propose an end-to-end switching model forwarding massive pairs nodes over a network. protection mechanism is employed improving survivability presence clouds, which may break line sight (LoS) HAPs We algorithm designing topology survivable network, given set The results demonstrate that, even though networks capacity use more resources, they are not necessary much expensive than those without terms equipment, i.e., devices, wavelength resource utilization.
