Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] as attached figure 1 As shown, it is assumed that all nodes are identical and have limited energy, the nodes themselves have location awareness and do not move after deployment, and the base stations are fixed and have no energy constraints. The elements of the first-level sealed price auction model are defined as follows:
[0021] Auctioneer: base station;
[0022] Bidders: nodes deployed in the monitoring area;
[0023] Auction items: each auction area in the monitoring area;
[0024] Winner: The bidding node with the highest bid in each bidding area wins and is determined as the cluster head of each area. If there are two or more bidding nodes with the same bid in the same bidding area, the bidding node with the smaller number wins;
[0025] The bidder's income: the bidder's valuation is a function of its remaining energy, which obeys the uniform distri...
