Abstract:
1. A method of executing an application in a terminal connected to a network, the method comprising: requesting synchronization information from a media access control (MAC) layer, by an application layer; providing time information which is managed for medium access control in the network from the MAC layer to the application layer in response to the requesting; synchronizing, based on the time information, the application in the terminal with another application on a second terminal connected to the network, the application and the other application being synchronized without exchanging packets between the terminal and the second terminal; and executing the application by the application layer based on the time information, wherein the network is a wireless local area network, and the time information is set based on a timestamp field value of a beacon frame, wherein the providing the time information comprises the MAC layer directly transmitting the time information to the application layer via a time synchronization interface without passing through any other layer.
