Role of Next Generation Advanced Wireless Techniques for Disaster Management in Smart Cities

The evolution of smart cities, driven by 5G and B5G, enhances quality of life and sustainability but faces challenges in disaster management. This chapter explores solutions using advanced communication technologies to ensure operational continuity post-disaster. Device-to-device (D2D) communication facilitates crucial message exchange between victims and relief teams without relying on base stations. Drone-assisted D2D cooperative communication (DA-DD-CC) improves reliability by incorporating drones as relays, enabling direct, drone-assisted, or combined links. Rate-splitting multi-user cooperation by drone (RSMUCD) integrates ratesplitting multiple access (RSMA) with multi-antenna drones to mitigate interference, optimize bandwidth, and boost reliability. This framework examines multi-cluster DA-DD-CC scenarios and evaluates RSMUCD against non-orthogonal multiple access (NCSD) and network-coded cooperation (NCC) schemes using metrics like outage probability, data rate, and throughput. Findings demonstrate significantly enhanced performance for disaster management in smart cities.
