1. A method for evaluating network quality, comprising:
generating a target network topology according to node information in a current network, the target network topology being a network topology structure in which a master node is directly connected to each sub node, wherein the node information comprises: channel usage information at a location of a node and network transmission information of the node, wherein the channel usage information at the location of the node comprises channel strength of a channel where the node is located, and the network transmission information of the node comprises signal strength of the node;
determining a network transmission cost of the target network topology as a first network transmission cost and a network transmission cost of the actual network topology as a second network transmission cost, according to the node information in the current network, the target network topology and an actual network topology of the current network comprises:
for each network topology, determining a maximum rate of each path in the network topology structure according to the channel usage information at the location of each node and the network transmission information of each node, comprises;
determining a signal strength factor of the path and a channel competition factor of the path, wherein the signal strength factor is used to indicate influence degree of the signal strength of the node in the path on the transmission rate, and the channel competition factor is used to indicate the influence degree of the channel competition in the path on the transmission rate; and
determining, a product value by multiplying a theoretically maximum transmission rate of the path, the signal strength factor of the path, and the channel competition factor of the path, as the maximum rate of the path; and

determining a quality evaluation result of the current network according to the first network transmission cost and the second network transmission cost.
