摘要: 针对LEO卫星组网负载分布不均衡的问题,提出一种基于遗传算法与线性规划相结合的网络流量负载均衡方法,并设计相应的负载均衡算法。在NS2中对其进行仿真,结果表明该方法能够使网络流量在星间链路上均匀分布,有效地均衡网络负载,提高网络平均吞吐率。

Abstract: Balancing network traffic is one of the important problems for LEO satellite network. An approach of balancing network traffic by combining the merit of Genetic Algorithm(GA) and linear programming is given. The corresponding load balancing algorithm is designed. And it is simulated in NS2. Result shows that it has good performance in distributing network traffic among ISLs for network traffic balancing, which is an advantage to improve network average throughput.

Key words: LEO satellite network, load balancing, routing algorithm optimization, Genetic Algorithm(GA), network simulation
