The driving unit generates column signal voltages in a first driving time period T1 determined according to the total number of mismatch values, and applies the column signal voltages in period T1 to the column lines when the row signals are applied respectively to four row lines during the period T1.

Abstract: Disclosed is a method of configuring a tree when a new sink is added in a wireless sensor network. The method includes selecting a first sensor node via which a path can run to a new sink with the smallest delay cost, if the new sink requesting the sensed information as a sink within an existing tree is added; thereafter determining whether a path connecting the first sensor node directly(direct path) to the new sink has minimal energy consumption, after selecting the first sensor node. A second sensor node via which a path can run to the new sink with the minimal energy consumption, if the direct path does not have the minimal energy consumption. Therefore, an optimal tree having the minimal energy consumption can be configured.

Abstract: 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.
