在面向节点群的混合网状应用层组播模型(Hybrid Mesh Application Multicast Model,HM-ALM)中设计并实现了确定性线性网络编码,探讨了网络编码对提高组播性能的作用.实验表明,网络编码能减少传输延迟和增强系统健壮性.使用网络编码后系统传输延迟减少了约50%;在系统动态变化时,正确接收数据的节点数可以达到最大值,系统能更快恢复稳定. 相似文献

团体结构是很多现实网络所具有的一个共性,为了更好的研究这一类网络,我们提出了一个新的带有团体结构的网络模型,用平均场方法分析了此网络的内度和外度,发现此网络具有无标度特性。 相似文献

The special any-polar resistive switching mode includes the coexistence and stable conversion between the unipolar and the bipolar resistive switching mode under the same compliance current. In the present work, the any-polar resistive switching mode is demonstrated when thin Ti intercalations are introduced into both sides of Pt/HfO2/Pt RRAM device. The role of the Ti intercalations contributes to the fulfillment of the any-polar resistive switching working mechanism, which lies in the filament constructed by the oxygen vacancies and the effective storage of the oxygen ion at both sides of the electrode interface. 相似文献
