The present invention proposes a software-defined airborne self-organizing network-oriented simulation method, which aims to provide a simulation method with higher simulation authenticity and stronger expansibility. The present invention is realized by the following technical scheme: firstly, using the wireless switching device supporting WiFi function provided by the Mininet-WiFi platform and the host terminal connected by the Ethernet link, and designing the airborne network simulation node by software definition, including the ordinary node and the controller node. Then the host terminal uses the built-in traffic generation tool to generate the data source for data transmission between nodes, and uses the port virtualization technology to build independent wireless, multi-hop Mesh links between nodes, and network in a mesh network. Complete the construction of Mesh data transmission network; on the basis of the wireless data transmission network, an out-of-band transmission method is used to independently create a control network parallel to the wireless data transmission network among all nodes, and control information is transmitted wirelessly to complete the software-defined airborne network. Simulation implementation of the environment.
Description
technical field [0001] The invention belongs to the technical field of Software Defined Network (SDN), and in particular relates to a simulation method for a software-defined airborne self-organizing network. Background technique [0002] A mobile ad hoc network is a wireless mobile communication network composed of a group of mobile nodes with wireless transceivers. It is temporarily established without relying on a preset infrastructure. The moving nodes in the network use their own wireless transceivers to exchange information. , when they are not within the communication range of each other, they can realize multi-hop communication with the help of other node relays. The main difference between the self-organizing network and the traditional mobile network is that the self-organizing network does not rely on any fixed network facilities, but performs network interconnection through the mutual cooperation between mobile nodes, that is, each node has both routers and hosts...
