In the apparatus and method, a request query of sensing data and timer parameters are received, local sensing data sensed in the sensor node in response to the received request query are detected, a driving time of a timer applying the timer parameters based on the request query is set, and the local sensing data are transmitted when the local sensing data do not overlap sensing data of a neighboring sensor node within a wireless reception range of the sensor node by overhearing the sensing data of the neighboring sensor node during the set driving time of the timer. Thus, since a data transferring path is selected considering the remaining energy of the node, the energy exhaustion of the node is distributed, thereby improve the lifespan of the network.
