Recently, the number of mobile subscriptions continues to grow along with an explosive increase in the mobile data traffic demand. Thereby, it creates significant network capacity shortage concerns for mobile network operators. In order to address this problem, it is essential to increase the network capacity at a low additional cost. Device-to-device (D2D) communication is believed to be a promising future mobile communication technology capable of creating various new mobile service opportunities and offload traffic from the cellular infrastructure. Efforts have been made by wireless engineers to meet this sociotechnological trend: Qualcomm has pioneered a mobile communication system known as FlashLinQ wherein wireless sense is implemented to enable proximity-aware communication among devices [1].
