Abstract

The invention discloses a clustering topology control method based on asymmetric energy distribution and mobile nodes. A distributed idea is introduced into a clustering type two-stage topology control process; and the mobile nodes with asymmetric energy distribution play a key role in prolonging the service life of a wireless sensor network. The method comprises the following steps of: 1, initializing the network, selecting a cluster head for the first time and forming a cluster structure; 2, maintaining the cluster, namely after the cluster structure is formed, the network starts to transmit information according to a relevant route protocol; and 3, reconstructing the cluster. In conclusion, after the nodes are gathered to guide the network to be initialized, the network starts to run completely in a self-organized mode, so that the mobile nodes and the cluster head with asymmetric energy are selected.
