ENERGY EFFICIENT MULTI-HOP CLUSTER BASED D2D COMMUNICATION FOR CATASTROPHIC AREA

Abstract

: Earth has been experiencing different types of disasters since time immemorial, causing death and destruction (to all types of infrastructure). Different parts of the world have been devastated by cyclones, earthquakes, landslides, and tornadoes. Over the past few years, energy and resource management has been the goal of research. Device-to-device communication is one of the emerging technologies that have the potential to play a crucial role in natural disasters by utilizing direct D2D communication to help achieve specific goals. Communication between D2D devices was designed for short-range use but can be applied to longrange applications through multi-hop relays. In addition, it is applicable to a number of practical applications including disaster management, uncoverage areas in cells, and battlefields. In order to optimize energy balancing and resource utilization, a cluster-based channel allocation scheme was used. Our communication infrastructure can work independently in case of any natural disaster, where primary infrastructure is damaged or not available. The proposed scheme "relays the communication traffic to the nearest base station through multiple hops. We applied the Dijkstra algorithm for the shortest path calculation. In order to calculate linkages from the source to the destination and to send data over reliable channels, the Link Calculation Method (LCM) is employed before transmitting frames. Our RF energy harvesting mechanism HSEH ensures energy is harvested from the most efficient source for maximum efficiency. The high strength signal of the RF source continues to ensure that energy is being harvested. Finally, we compared our simulation results with existing schemes. Results indicate that the proposed scheme outperforms the existing schemes in terms of consuming less energy while transmitting the data through a more reliable channel.
