为了准确的得到无线移动网络的抗毁性,需要对无线移动网络抗毁性测度指标进行优化和修正。采用当前方法对无线移动网络抗毁性测度指标进行优化和修正时,计算得到的无线移动网络失效链路总数和无线移动网络自然连通度的准确率较低。提出一种无线移动网络抗毁性测度指标优化修正方法,通过评价无线移动网络节点的重要性,得到无线移动网络的实际状况,对网络的实际状况进行分析,计算无线移动网络的连通度得到无线移动网络抗毁性测度。采用自然连通度代替连通度对无线移动网络抗毁性测度指标进行优化和修正。通过计算网络的冗余性和长度相同的闭环数据得到无线移动网络的自然连通度,根据自然连通度构建无线移动网络抗毁性测度模型,通过模型得到优化修正后的无线移动网络抗毁性测度。仿真实验结果表明,所提方法可准确的测得无线移动网络中的失效链路总数和自然连通度。

In order to accurately obtain the invulnerability of wireless mobile network, it is necessary to optimize and correct the measure index for invulnerability of wireless mobile network. This paper puts forward a method to optimize and correct the invulnerability measure index of wireless mobile network. By evaluating the importance of wireless mobile network node, the actual status of wireless mobile network was obtained. After analyzing the actual status of network, and the connectivity degree of wireless mobile network was calculated to obtain invulnerability measure of wireless mobile network. In addition, the natural connectivity degree could be used instead of connectivity degree to optimize and correct the invulnerability measure index of wireless mobile network. Then, natural connectivity degree of wireless mobile network was obtained by calculating the network redundancy and the closed-loop data with same length. Finally, the invulnerability measure model of wireless mobile network was constructed based on natural connectivity. Thus, the optimized invulnerability measure of wireless mobile network was obtained. Simulation results show that the proposed method can accurately measure the total number of failure links and natural connectivity in wireless mobile network.
