Multi-node communication method based on particle swarm optimization

The invention provides a multi-node communication method based on particle swarm optimization, and solves the problem that the channel load and competition risk are increased due to the randomness and unconscious information transmission mode of the existing multi-node communication network. The method comprises the following steps: 1) loading preset parameters; 2) causing all the nodes to access the network and send broadcast messages; 3) generating a starting node and a target node; 4) causing the starting node to randomly appoint a known node as a relay node and send information, after the appointed relay node receives the information, continuing to appoint the next-level relay node and send the information to the next-level relay node, sequentially transmitting the information among the nodes until the information reaches the target node; 5) calculating path fitness; 6) updating the path with high fitness into an individual optimal path; and 7) determining the path exploration capability.
