摘要: 基于分段连续监测的思想,提出一种在MANET中采用累计信任度判断节点间断性故障的监测方法,在单次监测中利用信息熵记录节点响应频率,通过共享信息熵,并根据伪空间距离联合诊断节点的间断性可知,该单次监测方法的效率高于已有方法,为进一步提高节点高速运动的监测准确性,通过分段连续监测,把单次监测结果作为分类器,计算节点的累计信任度,并通过累计信任度衡量节点的间断性。仿真实验结果表明,该方法是有效可行的。

Abstract: On basis of the series of subsection monitoring thought, this paper proposes an approach which uses cumulative trust to measure intermittent failure in Mobile Ad hoc NETwork(MANET). In the one-time monitoring, the information entropy is used for taking down the intermittent of nodes response, and a new distributed monitoring scheme with several collaborative detection methods based on pseudo-space distance are defined in this paper. This approach is much better than the old. In order to improve on the veracity of detection when nodes with high mobility, by the series of subsection monitoring, the monitoring results are seen as classifiers, and the intermittent failure is measured by the cumulative trust. Simulation experimental results show this approach is effective and feasible.

Key words: Mobile Ad hoc NETwork(MANET), intermittence fault monitoring, information entropy, cumulative trust
