1. A manager node comprising:
a first wireless communication unit configured to communicate based on a first channel;
a second wireless communication unit configured to communicate based on a second channel; and
a controller configured to:
establish a first network being a short-range wireless network along with a monitor node by using at least one of the first channel or the second channel;
receive battery data from the monitor node;
when a second network is detected, change the first channel to a third channel and change the second channel to a fourth channel, wherein a second modulation type and a second communication channel of the second network is same as a first modulation type and a first communication channel of the first network; and

when the second network is not detected, calculate a degree of degradation of the first channel, wherein, when the degree of degradation is outside a normal range, the controller is further configured to change the first channel to an auxiliary first channel and change the second channel to an auxiliary second channel based on a channel scan.
