Abstract

We propose a method for the topology design of free-space optical (FSO) mesh networks in order to enhance network reliability under a defined degree constraint of each FSO node. The methodology presented enlarges the minimum angle between adjacent links at each node. Simulation results show that, compared to other methods, the proposed algorithm not only provides a higher connectivity and lower delay for FSO networks but also makes the constructed FSO networks more tolerant in a dynamic environment.
