摘要 研究发现基于有限数据包统计出的收包率并不能准确体现当前节点工作的区间,而链路丢包特性在无须海量数据的前提下却可以比较精确地体现节点工作区间。通过模糊集理论可以实时地判断出当前工作区间,对不同区间内的丢包事件不一样的加权可以合理地反映出链路状况。研究结果显示,基于模糊区间识别的链路评估器能够准确反映当前链路状况,更具实用性。 The study found that the packet reception rate counted from limited packets could＇ t describe which region was the nodes in. While the characteristic of packets loss could describe the regions well based on a few packets. This paper identified the regions by fuzzy theory real-timely, and differently weighted in packets loss different regions. The results show that fuzzy region recognition based link estimator can describe the link quality well, and has more practicability.
