The invention provides a wireless sensor network clustering method based on first-price-sealed bid auction. According to the wireless sensor network clustering method, a base station serves as an auction party in a first-price-sealed bid auction model to broadcast auction information; nodes serve as bidders to send node numbers, node positions, residual energy and bidding areas to the base station; the base station examines the qualification of all the nodes taking part in bidding, calculates the optimal bids of the bidder nodes passing the qualification approval according to a bidding strategy, and simultaneously determines the cluster head node of each auction area (including a blank area); the base station broadcasts the cluster head nodes; the non-cluster head nodes serve as member nodes to join in a cluster by selecting the closest cluster head node, thereby completing the establishment of the cluster; the base station calculates information of next hop of each cluster head node by virtue of a CNP (Cheapest Neighbor Path) algorithm and broadcasts the information; and then the cluster head nodes send data to the base station in a multi-hop manner. The wireless sensor network clustering method based on the first-price-sealed bid auction improves the distribution rationality of the wireless sensor network cluster heads and the balance of node energy consumption, and effectively prolongs the survival time of a network.
