So far, many computation offloading with these increasing power demands. To overcome this problem, researchers gave birth to the Mobile Cloud Computing (MCC) frameworks using Bluetooth or Wi-Fi have been developed. research area. In this paper we advance on previous ideas, However, despite having reasonable bandwidth or data rate, by proposing and implementing the first known Near Field they are still facing some limitations, such as: the interference Communication (NFC)-based computation offloading framework. of other WiFi or Bluetooth devices, the Internet connection This research is motivated by the advantages of NFC’s short requirement in the case of MCC, which implies higher energy distance communication, with its better security, and its low battery consumption. We design a new NFC communication needs and higher delay [5], and the difficulty in detecting protocol that overcomes the limitations of the default protocol; available nearby devices for computation offloading through removing the need for constant user interaction, the one–way WiFi-direct or Bluetooth [8].
