Abstract

This paper first establishes a Markov model and a state transition matrix for the state of an optical communication system and calculates the steady-state probability of the network system by using the balancing features of the steady-state Markov model and its state transition probability.Then

it obtains the system steady-state probability through probability calculations in the light of the network topological structure and the protection mechanism information.Finally

on the basis of the assessment of the network system steady-state probability

it proposes a routing algorithm for the free-space optical communication system.This algorithm takes into consideration the fast mobility features of network nodes

link bandwidth

the shortest path and the constraints of the number of transceivers.The simulation study results indicate that the routing algorithms based on system steady-state probability assessments are superior to conventional ones in terms of reliability in practical applications.
