Abstract
The present disclosure relates to presenting a transceiver system for automatic tracking and dynamic routing for free space optical (FSO) communication to reduce the blocking probability and increase the percentage recovery of failed traffic. In one embodiment, for a FSO network including multiple transmitters and receivers, a logical topology is crustucted. Then the logical topology is optimized by calculating the traffic of each the lightpaths in the logical topology with a mesh architecture using a traffic matrix, such as using a mixed integer linear programming (MILP) formulation, to minimize a maximum traffic flow of the lightpaths interconnecting the nodes of the logical topology. Based on the optimized logical topology, routing is calculated to obtain a plurality of transmitter/receiver assignments for the transmitters and the receivers. Then the routing of the transmitters and the receivers may be controlled based on the corresponding transmitter/receiver assignments.
