Multi-hop wireless network topology simulation system for supporting heterogeneous multi-channel

Abstract

The invention discloses a multi-hop wireless network topology simulation system for supporting a heterogeneous multi-channel. The multi-hop wireless network topology simulation system comprises a plurality of heterogeneous channel subnet simulators; each heterogeneous channel simulator consists of an Ethernet switch and a topology control node, and is used for simulating the wireless multi-hop topology simulation of each type of heterogeneous channel subnets, and is accessed to each entity device via a virtual local area network, and is communicated with the topology control nodes; each topology control node is connected via a network, and is used for controlling and managing the topology relationship and the communication relationship of each subnet; a main topology control node is also in charge of generating, maintaining and managing position information and the like of the entity devices; each topology control node operates under an Ethernet promiscuous mode, and determines the data forwarding of the entity devices according to the topology relationship so as to complete the simulation and performance recording of various network topology structures in the multi-hop wireless network.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a multi-hop wireless network topology simulation system supporting heterogeneous multi-channel. Background technique [0002] With the development and progress of wireless communication network technology, new communication modes are also constantly developing. The common wireless communication mode is the cellular mobile communication network, which is a kind of network networking method in which users access base stations through wireless channels and use wide coverage. Its goal is to achieve wide-area wireless coverage under the premise of limited frequency and power resources. . Compared with the cellular network structure, the Adhoc mobile network does not need to set up fixed center base stations and other equipment, and the nodes exchange information and cooperate with each other to form a multi-hop mobile communication network, and its structure is more...

Problems solved by technology

However, since the human decision-making process is an indispensable link in the system, it is difficult for applied mathematics or computer programs to successfully imitate this link, so it has its limitations.

In addition, pure software simulation needs to re-implement the software on the test object on the simulation platform, which increases the workload

At present, many people try to use technologies such as artificial intelligence to improve the simulation quality of this link, but it has not yet matured.

This simulation mode has the highest degree of abstraction, the cheapest simulation cost, the shortest time spent, and the easiest way to do various variable control experiments, but there is a problem that the reliability of the simulation results is not high

However, the test bed simulation test is generally small in scale, it is difficult to simulate various topological structures in a limited space, and there is a problem of poor scalability
