On this paper, multi-hop cooperative strategies are adopted to enhance the physical-layer safety in 5G large-scale decode-and-forward (DF) relay networks with massive relays and eavesdroppers. The usage of graph concept is investigated to relieve the load of large nodes and simplicity the cooperative anti-eavesdropping transmission designs. In particular, a secrecy weighted graph is first hooked up in step with the network topology. Three eventualities related to distinct degrees of wiretapping capability are taken under consideration. For that reason, secrecy measurements are transformed into the weight of each edge and three green cooperative anti-eavesdropping strategies are then proposed for bodily-layer safety enhancement based on the shortest course algorithm, respectively. It's miles confirmed that the proposed cooperative anti-eavesdropping strategies have the property of low complexity and are extra appealing for large scale networks. Simulation effects highlight the efficiency and effectiveness of our designs. It's been proven that -hop transmission does not usually promise overall performance benefit in phrases of secrecy benefit. At the opposite, the proposed strategies are able to provide considerable improvement for unique instances, emphasizing the necessity of adopting multi-hop cooperative anti-eavesdropping techniques to improve the Physical-layer security.
