A Hybrid Load Balancing Algorithm Based on Artificial Bee Colony for LEO Satellite Networks

Abstract

With the development of satellite communication network, LEO satellite constellation network has become a hotspot. Due to the uneven distribution of traffic, which may cause the inter-satellite link congestion, load balance routing has become an important issue for LEO. To solve this problem, a hybrid routing algorithm ABC-HLBR is proposed, which combines global load balancing routing based on artificial bee colony with real-time 10-cal route dynamic adjustment based on two-hop link states. Simulation results show that the performance of network is improved by this algorithm in terms of the average end-to-end delay, the average drop rate and the total throughput.
