The invention provides an energy-efficient data transmission method in a crowd sensing network, which solves the technical problem of large scale sensing through radio communication by utilizing mobile population carrying intelligent equipment. Most present transmission schemes only utilize user movement paths and historic connection information to perform data transmission; however, the data dynamically changes, and is hard to calculate in advance, so that a stable link between two nodes is particularly difficult to establish. In order to realize energy-efficient information transmission, the scheme configures a proper quantity of static nodes according to an Achimedean spiral which employs the center of a map as a starting point to increase node contact probability and a communication coverage scope. The method can effectively improve an information transmission success rate in a crowd sensing network, and meanwhile reduce network energy consumption.
