A routing method in a wireless sensor network where sensor nodes are grouped into cells is provided. Upon receipt of detected information to be transmitted to a destination, a sensor node determines whether a cell to which the destination belongs is one hop away. If the cell of the destination is not one hop away, the sensor node selects a cell set close to the destination from available neighbor cells to which the detected information can be forwarded, selects a cell from the cell set according to energy densities of the cells in the cell set, and forwards the detected information to a main sensor node of the selected cell.
