Problems solved by technology

[0005] Disadvantages of existing methods: the DRNG method needs to know a large number of node information and the calculation vehicle is relatively large
This is difficult to implement for sensor nodes with limited size and resources.

Embodiment Construction

[0058] The efficient wireless sensor network topology control method of the present invention combines the clustering method in the topology control and the power control method, and is specifically divided into the following steps:

[0059] 1). Divide the network into clusters and elect cluster head nodes: nodes in the network become candidate cluster heads with the probability initially set, and then broadcast the message that they are cluster heads with the maximum power. If a better cluster than itself is found within the transmission radius head, then give up the competition of the cluster head, otherwise it will become the cluster head;

[0060] 2). Construct the intra-cluster network: the node selected as the cluster head broadcasts the message that it is the cluster head, and the ordinary nodes decide to join a certain cluster according to the signal strength, and send the join message to the cluster head, and the cluster structure is formed at this time;

[0061] 3). ...
