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。
In order to solve the problem of uneven distribution of topological structure of current laser network nodes, a balanced routing topology tree based on routing tree is designed based on the study of laser network structure. The structure of the routing tree of laser network nodes is constructed, an equalization parameter is defined, and the equilibrium distribution of nodes is transformed into a problem of maintaining the equalization parameter not greater than one. By fitting the node information of each sub-tree in the routing tree, the knowledge of fitting information is excavated. The classification is that the new node chooses the path to the routing tree to implement the second maintenance of the equalization parameters and update the node topology structure. Experimental results show that the proposed routing tree method has excellent node balance ability, which can effectively prolong the service life of laser communication network.
