D2D Communication Implementation for Future Cellular Networks (5G)

Inhalt:
New applications with increasingly stringent quality of service (QoS) requirements continue to motivate the evolution of cellular networks. Future cellular networks (5G) are envisioned to offer high reliability (10 (exp −9)), low latency (≤ 1 ms) and enormous capacity for the anticipated massive number of devices. The new device-to-device (D2D) communication concept, where devices in close proximity communicate directly with each other, presents a prime enabler for the stringent QoS requirements. Implementation and validation of D2D communication performance according to 3GPP standards is critical for the development of future cellular networks. In this paper, we discuss implementation of D2D communication within the existing cellular networks based on software defined radios (SDRs) using open-source software packages of long term evolution (LTE). The results indicate 2 2% better throughput and 63 % latency improvement for D2D communication compared to that in the legacy cellular network.
