The invention discloses a node random network access method suitable for a multi-hop self-organizing dormant wireless sensor network. The method includes the following steps that: a node to be networked sends a network access request message to a coordinator; after receiving the network access request message, the coordinator calculates the sleep time required for synchronization of the node, sends a network access response message to the node to be networked, and sends a node pre-network access message to an upper computer; after receiving the network access response message returned by the coordinator, the node to be networked sends a network access confirmation message to the coordinator, and then starts sleeping according to the sleep time in the network access response message to realize the synchronous wake-up with a sensor node in the network; and after receiving the network access confirmation message, the coordinator sends a node network access success message to the upper computer. According to the
