摘要
Provided is a reliable and energy efficient data routing apparatus and method for a sensor node in a wireless sensor network. The method includes: receiving route setup messages including residual energy information of each of one or more neighboring sensor nodes within a wireless reception range of the sensor node from the neighboring sensor nodes for a predefined reception waiting time; selecting a parent node for routing from among the neighboring sensor nodes according to the residual energy information of each of the neighboring sensor nodes; and transmitting the sensing data to the selected parent node. Accordingly, since a data transmission path is selected by considering residual energy, energy consumption can be dispersed across the wireless sensor network to extend the lifetime of the wireless sensor network and a detour can be used to improve data transmission reliability.
