摘要
波动性是网络拓扑层抗毁性的一项重要参考指标。针对军事通信网拓扑层波动性评估问题,将传统评估算法改进后提出了一种基于路径加权的新算法。不再将网络所有链路的重要程度等量齐观,而是通过网络节点间两两通信,计算出每条链路的权值进而得到与链路相连节点的权值(波动性度量值),用所有节点权值的均方差评估网络波动性。最后基于布尔行列法对复杂网络路由探寻的准确性,分别将新算法与传统算法应用于复杂网络波动性评估并进行比较。结果表明:传统评估算法具有不准确性,而新的算法不仅评估量化更为细致,而且对节评估准确无误,新算法完善可靠。
Network volatility is an important reference index to the property of network topology survivability.An evaluation algorithm based on path weight is proposed to solve the problem of topological fluctuation in military communication network after improving the tradition one.The importance of each link is unequal and the weight of each link is calculated through the communication between the network nodes to get the volatility measure linked with nodes.The network volatility is assessed by the mean square error of all the nodes.Routing algorithm based on Boolean row method has the exact characteristics to extend the algorithm to complex network volatility assessment.In the end,the assessments of the new algorithm and the traditional algorithm are compared and analyzed.The results show that the traditional algorithm can not accurately evaluate the complex network volatility while the new algorithm has better discrimination and accuracy,which can be used in complex network topology volatility assessment.
