A sampling rate allocation method for a wireless sensor network is provided. In this method, a distributed computing method is adopted to allow each node to calculate and obtain its decision table and energy table and upload its energy table to its parent node, and finally, the number of samples to be provided by all the child nodes is determined according to the decision table of the root node and a total sample number. Compared to the conventional techniques, the present invention provides a wireless sensor network which has longer life time and can meet the requirements to both the total number of samples and the fairness.
