Description

technical field [0001] The invention relates to the technical field of computer simulation, in particular to a method for designing semi-physical simulation elements facing a large-scale unmanned swarm network. Background technique [0002] Large-scale unmanned swarm network is based on mobile ad hoc network technology, also known as mobile Ad Hoc network, which is a special wireless mobile communication network system. All nodes in the self-organizing network have the same network function and equal status. It does not need to set up any control center, nor does it need fixed and wired facility support. It has strong robustness. The nodes in the ad hoc network not only have the data sending and receiving functions of ordinary wireless terminals, but also have the routing and forwarding capabilities of messages, and maintain the operation of the network. As a wireless channel-based, dynamically changing autonomous network, its technology can provide the technical basis and ...
