Window Classification Strategy RWA Algorithm Based on Bee Colony in Satellite Optical Networks

This paper proposes a bee colony optimization RWA algorithm based on window classification strategy. The algorithm can use the window classification strategy for node selection, and adaptively adjust the fitness function for different services to evaluate the existing feasible solutions. Simulation results show that this algorithm has superior performance in terms of blocking rate and delay.

I. Introduction

The continuous advancement of technology in society has led to an increase in the demand for network communication, the traditional terrestrial networks cannot fully meet the needs of production and life in many scenarios, and the satellite network has become an indispensable and important part of network communication with its advantages of large range, ultra-long distance and system robustness [1], [2]. The traditional microwave links used by satellites can hardly meet the demand for higher capacity, longer distance, faster rate and safer services. Laser communication, on the other hand, has significant advantages in terms of transmission distance, transmission capacity, transmission rate, etc. Therefore, laser communication becomes an important application for establishing satellite optical networks.
