Free space optical communication (free space optical communication, FSO) is an infrared laser wireless transmission technology to carry high-speed signals , low cost, large capacity, simple design , easy access , and other advantages . FSO network with both traditional mobile Ad Hoc network self-organization , independent networking capability , no center , invulnerability , etc. , also taking advantage of the the FSO high quality directional radio transmission characteristics of the network physical layer transceiver control . Thus , in the field of wireless communication , FSO network technology has been more and more attention . In this paper, the study of traditional mobile Ad Hoc network topology and routing based on cutting-edge , with the current the FSO network technology development , in-depth study of the the FSO network initialization algorithm . Mainly analyzes the formation of a distributed topology algorithm, to establish a connection by iteration , until the formation of a tree topology , in military applications provide fast connectivity . The algorithm in Visual C environment for modeling and simulation , and the results were analyzed , improved proposal , and ultimately get the optimal topology . On this basis, proposed an effective routing algorithm , and illustrated . Finally, demonstrate the correctness of the algorithm derived for degree - constrained FSO network initialization , and bottom-up minimum spanning tree algorithm is the preferred method .
