The scenarios have a different number of FSO and RF links. The aim is to identify an optimum scenario to effectively improve the end-to-end reliability of the multi-hop hybrid FSO/RF system. Outage performance is investigated for the scenarios under various weather conditions through numerical examples. It is identified that for a given link distance the end-to-end outage probability is minimized when using a hybrid FSO/RF link between every two successive nodes of the multi-hop system, and this requires the maximum number of FSO and RF links to be deployed.enginfo:eu-repo/semantics/restrictedAccessConference paper838700037736740001810.1109/IWOW.2015.7342271Multi-hop transmissionDecode-and-forward (DF)Hybrid free-space optical/radio frequency (FSO/RF)Outage probabilityWeather condition2-s2.0-84960929333
