Method for Wireless Automatic Networking

A method for wireless automatic networking, wherein a network adopts a layered network structure, including a relay layer, a routing layer and a terminal layer, a star connection is adopted between a relay node on the relay layer and a routing node on the subordinate routing layer, and a star connection is also adopted between the routing node and a terminal node on the subordinate terminal layer;

• and
• the method comprising:
• pre-selecting N working channels between working frequency bands as N hopping frequencies;
• setting an RSSI threshold of the routing node, wherein when an RSSI detected in real time is higher than the RSSI threshold, the routing node determines that it is interfered, reports to the corresponding relay node to apply for frequency hopping, and the relay node hops and sends a beacon to the routing node, and if the routing node does not receive the beacon, the routing node hops to search and track until the beacon is received, to ensure that the relay node shares the same channel with each routing node, and the routing node locks the shared channel;
• establishing working frequencies of the routing node and each terminal node on the shared channel, calculating an optimal power value of the routing node and each terminal node during communication respectively, and then testing whether each routing node conflicts with the frequencies of other routing nodes under the premise that the transmit power of the routing node and the terminal node is optimal, and if so, the frequencies of the conflicting routing nodes are reallocated until the frequencies of the routing nodes do not conflict;
• and
• loading, by the relay node, the frequency of each routing node successively, wherein when the routing node receives a frequency value, it first notifies each terminal node to change frequency on the shared channel, and confirms that each terminal node receives frequency-changing data, and then automatically changes the frequency from a shared frequency to a new frequency;
• after a polling test is performed on each terminal node on the new frequency, the frequency being successfully loaded is reported to the relay node;
• and after all the routing nodes complete frequency loading, the network enters a normal working state.
