Abstract:
Device-to-device (D2D) enables direct communication between two-user equipment (UEs) with or without the involvement of a base station (BS). D2D communication is a vital paradigm to design a reliable public safety network (PSN) and support several services in the sixth generation (6G) systems such as target monitoring, emergency search and rescue, etc. In this experimental study, we demonstrate a cooperative D2D communication system in an emergency scenario to disseminate important information (e.g., the number of people, their IDs and current location) from an affected zone to a deployed command centre in the absence of a BS. We suggest context-aware proximity services-based direct discovery along with unmanned aerial vehicles (UAVs) as a possible solution to implement the future PSN in 6G. Furthermore, we characterize the performance of direct discovery in terms of connectivity reliability and latency in emergency scenarios. Our results show that the discovery ratio is always higher than 90% for SNR values above 20 dB and reaches 100% for SNR values of 23 dB. The end-to-end delay is a low as 18 ms when there is no relay node between two UEs, and increases linearly with the number of hops. Under specific emergency scenarios, the impact of this work is that it is possible to deploy the equipment, establish connectivity, and pass information from the affected zone to deployed command centre in approximately one minute and forty seconds in a real-time lab environment, and four minutes and thirteen seconds in the tested real-life outdoor scenario.
