一种激光网络中的节点拓扑结构分布方法设计

Design of node topology distribution in laser network

针对当前激光网络节点拓扑结构分布均衡化差的问题,在研究激光网络结构的基础上,设计了一种基于路由树的激光通信网络节点均衡拓扑分布方法。构建激光网络节点的路由树结构,定义一种均衡参数,将节点均衡拓扑分布转化为维持均衡参数不大于1的问题。通过拟合路由树中各子树的节点信息,对拟合信息进行知识挖掘,分类型为新节点选择进入路由树的路径,以实施均衡参数二次维护,更新节点均衡拓扑分布结构。实验验证表明,所提路由树方法拥有优异的节点均衡能力,可有效延长激光通信网络使用寿命。

For the poor equalization of node topology distribution in current laser network,on the basis of laser network structure,this paper designs a node equalization distribution method in laser communication based on routing tree. Build routing tree structure of laser network nodes,define a balanced parameter,and the balanced topological node distribution can be converted to maintain equilibrium parameter which isn＇t bigger than 1. By fitting the nodes information of each sub-tree to mine fitting information knowledge and choose path to routing tree for new nodes according to types. Update node balanced distribution topology structure through secondary maintenance of balanced parameters. Experiments show that the proposed routing tree method has excellent node balancing ability,which can effectively prolong the service life of laser communication network.
