An electronic device according to an embodiment may include at least one wireless communication module configured to transmit and receive a wireless signal, at least one processor electrically and/or operatively connected to the wireless communication module, and a memory electrically and/or operatively connected to the processor and configured to store instructions executable by the processor. When the instructions are executed by the processor, the processor may perform a synchronization with an external electronic device based on time synchronization function (TSF) timer associated information of a reference access point (AP). The processor may further form a neighbor awareness networking (NAN) cluster including the electronic device and the external electronic device based on a result of performing the synchronization. The NAN cluster may be maintained in a non-master mode based on TSF timer information of the reference AP. Other embodiments may also be possible.
