Networking method based on power control of heterogeneous networks

The invention provides a networking method based on power control of heterogeneous networks. According to the networking method, first, a communication device which is located in a first network and can be communicated with nodes in a second network is used as one node in the second network; probabilities of networking communication between all the nodes are determined according to the communication range covered by all the nodes in the second network and the position relation between all the nodes; next, power values of networking communication of all the nodes which can conduct networking communication with the communication device are determined according to all the probabilities and the conditional information of communication of the nodes corresponding to all the probabilities, and a power control table is formed according to the determined power values corresponding to all the nodes; the power control table is sent to the communication device. In this way, all the nodes in the second network can be subjected to networking at appropriate power values.
