Complex task collaboration solving method based on reverse auction strategy in wireless sensor network

The invention relates to a complex task collaboration solving method based on a reverse auction strategy in a wireless sensor network, which comprises four stages of: (1) laying tasks: a center cluster layers and divides the tasks according to the DAG graph of the tasks; (2) determining a collaborative cluster: the center cluster will send a message to a surrounding hop cluster for requesting assistance if the energy consumption degree of the center cluster exceeds a setting threshold; if the energy consume degree of the surrounding hop cluster does not exceed the setting threshold, the surrounding hop cluster will be the collaborative cluster of the center cluster; (3) distributing the tasks to a cluster head: the tasks in each layer is firstly disposed by the center cluster which distributes the tasks not distributed to the collaborative cluster; (4) distributing the tasks to nodes in the cluster by the cluster head: a second low-price sealing auction method is applied to the distribution of the tasks in the cluster, the cluster head is as an auction, the nodes in the cluster are as bidders, the auction selects the bidder bidding the lowest price to win the bidding, and the winning side trades at the second low price. The method achieves the energy balance of network nodes and prolongs network lifetime.
