Problems solved by technology
[0004] At present, there are also some studies that further abstract the modeling of the communication network around the external performance, and embed it into other simulation applications (see James W Jones, "JWARS Communications Modeling", in Proceedings of the Spring SIW, 1999, PPT 99S-SIW -181), but the abstract methods used in these studies are often too simple, and the factors that have a greater impact on communication effects, such as interference, damage, load, and topology, are not considered enough, especially the internal mechanism simulation and external performance have not been established. The connection between simulations cannot make full use of the results of internal mechanism simulations, making it difficult to guarantee credibility

Embodiment Construction
[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0036] Such as figure 1 As shown, the present invention provides a method for shielding internal mechanism and credible communication network simulation. The method comprises the steps of:
[0037] Step 1, abstract the communication network into communication subnet, communication hub and user node;
[0038] Step 2, input relevant parameters;
[0039] Step 3, calculate the communication performance when the simulation is running.
[0040] Wherein, the step 1 specifically includes abstracting the communication network into communication subnets, communication hubs and user nodes. Among them, the communication subnet is a logically independent division of the communication network, which can generally be constructed according to different links; the communication hub mainly undertakes the functions of communication exchange and relay, and is a physical enti...

The invention relates to a communication network simulation method and a communication network simulation system. The communication network simulation method comprises the following steps of: 1, abstracting a communication network into a communication subnetwork, a communication center and a user node; 2, inputting parameters required by simulation run; and 3, calculating communication efficiency during the simulation run. By the method and the system, simulation modeling of the communication network can be realized, the development cost of communication network simulation application can be reduced, and the credibility can be improved.
Description
technical field [0001] The invention relates to the field of computer simulation, in particular to a communication network simulation method and system. Background technique [0002] The core of communication network simulation is to use computer simulation technology to simulate the communication network, calculate the communication performance (such as information transmission delay, etc.), and use it as the basis for evaluating and optimizing the communication network. Simulation-based methods have the characteristics of low risk, high efficiency, low cost, repeatable experiments, and easy quantitative analysis, and have become a powerful means of analyzing and evaluating communication performance. [0003] At present, the communication network simulation is mainly based on professional simulation tools (such as OPNET), modeling and simulating the internal mechanism of the communication network (including routing and other underlying protocols and algorithms), and then ca...
