A Novel Simulated Annealing based Routing Algorithm in F-SDNs

In recent years, routing algorithms have attracted tremendous research attentions in Flying Ad hoc Networks (FANETs) in order to provide efficient networking to fulfill the demand of Intelligent Transport System (ITS). Due to the lack of a global network information in FANETs, existing routing algorithms still have many issues in finding the optimal next-hop node, suffering low packet delivery rate and high delay. With the inclusion of Flying-Software Defined Network (F-SDN), providing global network information has eased the routing and forwarding of data for Unmanned Aerial Vehicles (UAVs). In this paper, we introduce a new routing algorithm by our Modified Simulated Annealing (MSA) algorithm to increase performance of networking in dense environments. The experimental results show the proposed algorithm outperforms the standard algorithm in the finding of routing paths in F-SDNs.
