Dynamic routing method for laser communication network based on load balancing

针对激光通信系统节点中数据流量不均衡导致的通信拥塞等问题,提出基于负载均衡的激光通信系统动态路由方法。根据激光通信系统中各节点的负载状态,利用贝叶斯分类算法对通信节点进行分类,依据分类结果将通信任务从重负载节点调配至轻负载节点,减少任务执行的等待时间;根据节点负载均衡状态,结合激光通信系统数据包传输链路分析,构建通信链路性能度量模型,综合考虑链路空闲度与生存时间,通过节点动态组合减少通信拥塞,延长寿命。实验结果表明,所提方法的负载均衡性能较好,且激光通信系统端到端时延均值与丢包率均小于实验对比方法,有效提高了通信可靠性。

Aiming at the problems of network congestion caused by unbalanced data traffic in laser communication network nodes,a dynamic routing method based on load balancing for laser communication network is proposed. According to the load status of each node in the laser communication network,the Bayesian classification algorithm is used to classify the network communication nodes,and the communication task is deployed from heavy load node to light load node according to the classification result,which reducing the waiting time of task execution. Combined with the analysis of the data transmission link of the laser communication network,constructs the communication link performance measurement model based on the load balancing state of nodes. Comprehensively considers the link idleness and the survival time to reduce the network congestion and dynamically extends the network lifetime through dynamic combination of nodes. The experimental results show that the proposed dynamic routing method has better load balan- cing performance,and the average end -to -end delay and packet loss rate of the laser communication network are smaller than experimental comparison method,which effectively improves the network reliability.
