Method and apparatus for executing an application automatically according to the approach of wireless device

Abstract

A home system is provided. In a method of executing an application, information for executing the application is received from a device when accessing of the device is sensed, and the application is executed based on the received information. Accordingly, when a user merely brings a wireless guest device near to or in contact with an access point or a wired home device, it is possible to allow the wireless guest device to simultaneously automatically set an optimum security environment for a wireless network and execute an application that the user desires.
