This work adopts the paradigm of cloud computing over the framework of Device-to-Device (D2D) communications in LTE-Advanced to enable mobile devices to offer network services to nearby devices, thus acting as mobile cloudlets, and to offload cellular traffic from the core network. Hence, any mobile device seeking a new service can search and discover for nearby services with the help of the LTE-A network. From an implementation point of view, our solution fits very well within the 3GPP standards as it utilizes its network elements designated for offering proximity based services. Our experimental results proved the efficiency of our system in helping mobile users discover needed services offered by nearby providers.
