复杂环境中Ad hoc网络的数据完整性加速试验

为了快速测量Ad hoc网络在任务想定下的数据完整性,根据相关定义给出了数据完整度解算过程,并基于相似理论建立相似现象,推导了有效信噪比、流量与节点移动速度等关键参数的相似模型,综合得到了Ad hoc网络数据完整性相似模型.为验证上述模型的效果,应用OPNET仿真平台设计了一个救灾Ad hoc实验,仿真结果表明正常应力作用下的原始网络和短时高应力作用下的相似网络数据完整度误差小,且相似模型的效用不随故障阈值、应力增加倍数以及网络拓扑结果的变化而变化. 

Accelerated testing for data integrity of Ad hoc network in complex environment

In order to evaluate the data integrity of Ad hoc network under its mission scenarios in an efficient way, an accelerated testing method was proposed. The similarity models for the key parameters of data integrity, i.e. the effective signal-to-noise ratio, the traffic and the moving speed, were derived based on the similarity theory, which finally composed the similarity model of data integrity. The case study on a relief Ad hoc network verified the effectiveness of the similarity model based on OPNET simulation tools. The results show that the error between the original network and the similar one is very small, and the effectiveness of the similarity model does not change with the failure threshold, stress increase times and the topological structure.
