Abstract

The control apparatus is provided with a channel quality test module for collecting power consumption between adjacent gateways of the data transmission routes, a communication interface for collecting data delay of the respective gateways of the data transmission routes by performing data communication with the gateways, a memory for storing a gateway routing table containing the multiple data transmission routes, the power consumption collected by the channel quality test module, and the data delay collected by the communication interface, and a processor for adding priority to the multiple data transmission routes in the gateway routing table stored in the memory on the basis of the power consumption and data delay stored in the memory.
