The present invention relates to a method for minimizing channel interference between heterogeneous wireless devices by dynamically managing a wireless channel and transmitting data by efficiently using the channel. A method for managing a channel of a reception node included in a wireless sensor network includes: a step of counting the number of times that data frames cannot be received in at least one channel among the channels being used in the wireless sensor network; a step of changing a state of a first channel to unavailable if the number of times that data frames cannot be received from a first transmission node through the first channel among the channels reaches n; and a step of notifying that the first channel is unavailable to the first transmission node through a second channel among the channels. According to the present invention, the reliability of data transmission can be improved by improving the data transmission success rate of the wireless sensor network by avoiding interference between heterogeneous wireless networks in a channel hopping mode. |
