Public Safety Communication (PSC) is responsible to provide reliable communications between the first responders and the victims in public safety scenarios. Some state-of-the-art wireless communication technologies, such as Cross-Technology Communication (CTC) and Device-to-Device (D2D) communication, are providing more possibilities of the connectivity amongst different communication devices. For instance, CTC enables communications between heterogeneous wireless devices (e.g. Wi-Fi, ZigBee, and Bluetooth) operating in the same ISM band, and D2D communication allows direct communication between wireless devices without traversing a base station. These features make them be promising to be applied for reliable PSC network establishments. They can replace those traditional wireless communication technologies which are not specially designed for PSC networks. In this research work, we propose a novel PSC network architecture based on CTC and D2D communication technologies. To be specific, we propose a novel device clustering scheme to expand the coverage of the PSC network. Cluster heads and cluster gateways in the scheme are chosen from a group of user equipment (UE) based on particular metrics, e.g., residual battery power, received signal strength indicator, etc. Moreover, we propose a scheduling scheme for managing the UE in our PSC network to improve energy efficiency. The simulation results demonstrate that our proposed PSC network architecture can provide reliable public safety communications with high energy efficiency.
