Device to Device Disaster Management: Squirrel Search Algorithm Approach

Cellular networks can overcome their bandwidth bottleneck problem through the use of device-to-device communication paradigm. In instances of traffic congestion and natural calamities, these technologies aid in preserving the essential connection between user devices. It overcomes the need for nearby user equipment (UEs) to send their radio signals through the BS or the core network to facilitate immediate information sharing. This work addresses relay-assisted device-to-device (D2D) communication in disaster scenarios. An adaptive architecture for D2D communications is developed that can be used in emergency conditions. In particular, fuzzy based a new nature-inspired squirrel search algorithm (SSA) is proposed for CH selection. By using this method, a UERCH is selected and the information is passed through this relay CH. To enable communication between victims of natural catastrophes and emergency personnel, the architecture uses an SDN controller to help it establish a multi-hop routing path. Additionally, we offer a public safety scenario in which a portion of the network goes down as a result of exceptional occurrences like natural disaster, showcasing the robustness and potential of our proposed method. On comparing with the existing approach, the simulation results show that the suggested method achieves low energy usage with enhanced device battery life.
