Next generation 5G networks contemplate to exploit millimeter Wave (mmWave) for a massive increase in data rates but its inherent characteristic of line-of-sight (LoS) brings up the challenge of directional synchronization of transmitters and receivers. In this letter, we propose a fusion of social Internet-of-Things and device-to-device (D2D) communications, shaping social D2D to tackle mmWave LoS challenge using an independent “reliable relay” scheme. We introduce distributed social network of devices and propose social-communication graph formation and autonomous trustworthy relay procedure. Utilizing reliable relay, a non-LoS device can communicate to 5G networks without compromising the contents privacy. Our analysis demonstrates that agile reliable relay substantially improves the capacity gain and data rate and can be an integral part of existing relay selection schemes. NS3-based simulations validate the proliferation in throughput with minimum additional delays.
