Free Space Optical (FSO) based mesh networks are emerging as a significant new technology for establishing and/or enhancing the optical backbone network without laying optical fibers. However, due to the strict line-of-sight requirement for establishing such links, they are susceptible to degradation due to fog or other temporary obstructions. Good routing protocols can have far-reaching effects on the performance and reliability of these degree constrained FSO mesh networks. In this work we have used a dynamic Geographic Routing Protocol with flow control in order to achieve low average packet delay, high adaptability to changing atmospheric parameters and low packet loss, based on a given physical layer topology and external traffic demands
