Decentralization communication method and system based on wireless ad hoc network

The invention relates to the technical field of communication, and discloses a decentralized communication method and system based on a wireless ad hoc network, and the method comprises the steps: obtaining an address code of a node, and building a communication connection topological graph according to the node and the address code of the node; the address code comprises an encrypted character string and address sending time, and the encrypted character string is formed by encrypting a physical address of the node; generating a communication network of the node according to the address code of the node; and obtaining a source node and a target node in the communication connection topological graph, and generating a communication connection path according to the communication network of the source node and the communication network of the target node, so that the source node and the target node communicate through the communication connection path. According to the invention, the communication connection topo
