A heterogeneous computing method includes performing offline learning on an algorithm using compilations and runtimes of application programs, executing a first application program in a mobile device, distributing a workload to a central processing unit (CPU) and a graphic processing unit (GPU) in the first application program, using the algorithm, performing online learning to reset the workload distributed to the CPU and GPU in the first application program, and resetting the workload distributed to the CPU and GPU in the first application program, corresponding to a result of the online learning.

Abstract: Provided are a method for providing augmented reality (AR) services, and a user terminal and an access point using the same. The user terminal according to an embodiment of the present invention includes a reception unit that receives AR-related information broadcast by at least one access point (AP), a photographing unit that photographs an image of an object to obtain the photographed image, and a comparison unit that compares the obtained image of the object with the AR-related information received from the at least one AP to identify the object.

Abstract: A communication method in a wireless local access network (WLAN) and a wireless apparatus therefor. According to the communication method, a station (STA) receives frames each of which contains upper layer service discovery protocol information from one or more access points (APs). The STA transmits an association request frame to an AP which is selected based on upper layer service discovery protocol information received from the APs. Then, the STA proceeds with an association process with the selected AP. The upper layer service discovery protocol information may be represented in a bitmap scheme whereby each of service discovery protocols contained in the upper layer service discovery protocol information is indicated as to whether it is supported by the AP; an enumeration scheme whereby identifier of each of supported service discovery protocols is included in the upper layer service discovery protocol information; or a hybrid scheme.

Abstract: An apparatus for providing information about an available service using a proxy server and a method thereof. The apparatus includes an available service checker, a database, an available service searcher, and an available service broadcaster. The apparatus may provide information through the proxy server regarding available services of a device that is not currently connected to a basic service set (BSS), thereby preventing generation of excessive amount of traffic.

Abstract: Disclosed is a message communication method of transmitting and receiving a certain message, independently of any network, without privacy invasion issues. The method includes generating vendor specific data on the basis of input information, adding the generated vendor specific data to a P2P information element of a probe request frame, and transmitting the probe request frame to another message communication apparatus. Thus, an apparatus conforming to a Wi-Fi Direct standard may transmit/receive a certain message to/from another terminal independently of a use region, a use environment, and a network of a large telecommunication vendor, without privacy invasion issues.
