Abstract:
A method for transmitting and receiving data between a first cluster and a second cluster by a first device of the first cluster, the first device, and a second device are provided. The method includes notifying a second device of the second cluster of a presence of the first device through a discovery beacon, transmitting information about a service that the first device provides to the second device, receiving a data path setup request from the second device that updates a channel active period to be equal to a channel active period of the first device based on the discovery beacon, and transmitting a data path setup response to the second device in response to the data path setup request, wherein a data path is established between the first device and the second device and is used to transmit or receive data to/from the second device.
