The simulation method has the advantages of flexible configuration, good expandability, transparency for a low level and high reusability. The simulation method ensures the consistency of the simulation environment and real environment; the simulation results are more accurate, so the simulation reliability is improved; and the workload of simulation workers is reduced, the mutual portability of the application in the real environment and the simulation environment is easily realized, and the repeated work of developing a set of application for the simulation environment and the real environment respectively is avoided.

Description

technical field [0001] The invention relates to a wireless channel simulation method based on a virtual network card under a Windows operating system, belonging to the technical field of information communication. Background technique [0002] With the application of wireless IP networks more and more widely, the modeling and simulation of these networks has become an important link. It is a widely used method to simulate the wireless channel by using the wired channel of Ethernet. [0003] The TCP / IP protocol family is divided into four conceptual layers, from bottom to top: network interface layer, inter-network layer, transport layer, and application layer. There is no detailed definition for the lowest network interface layer. Since the bottom layer is closely related to the hardware, the functions of this part are usually completed by the network interface card and the corresponding network card driver. Roughly equivalent to the physical layer and data link layer in ...

AI Technical Summary

Problems solved by technology

In the actual simulation environment, the implementation of the bottom layer often faces two problems: first, the real network interface card and related drivers are often not available in the simulation stage; second, the wireless network interface is not necessarily provided in the form of a network interface card. , while the built-in TCP / IP protocol of Windows is provided in the form of NDIS (Network Driver Interface Specification, Network Driver Interface Specification), which cannot be directly used on devices that do not conform to the NDIS specification
