Embodiment Construction

[0091] It will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0092] combine figure 1 As shown, a wireless energy-carrying relay system with multiple eavesdropping nodes includes a signal source (S), a relay node (R), a destination node (D) and n potential eavesdropping nodes (E 1 ,E 2 ,...,E n , n is a positive integer greater than or equal to 1). After receiving the source signal, the relay node processes the signal and sends it to the destination node. Due to the broadcast nature of wireless channels, potential eavesdropping nodes will also receive the signals sent throughout the transmission.

[0093] The whole communication process can be divided into two stages. The first stage is that the signal source sends a signal to the relay node; the second stage is that the relay node sends a signal to the destination node. The transmission time of the two stages is equal, which is set to T.

[0094] In the first stage, ...

Abstract

The invention discloses a wireless energy-carrying relay system containing multiple eavesdropping nodes and a resource allocation method thereof. Aiming at the potential safety hazard caused by the eavesdropping nodes in the wireless energy-carrying relay system, the time allocation and the energy absorption efficiency of the system are determined from the perspective of optimal safety energy efficiency, and a transmission resource allocation scheme is designed. Simulation results show that the system security energy efficiency can be significantly improved by using the transmission resource allocation method in the invention.

Description

technical field [0001] The present invention relates to the technical field of secure transmission of wireless communication systems, in particular to a resource allocation method in a wireless energy-carrying relay system with multiple eavesdropping nodes, which determines the time allocation and energy absorption efficiency of the system based on the principle of maximizing security and energy efficiency. Background technique [0002] With the further development of wireless communication, the security of wireless communication becomes more and more important. The traditional method of using application-layer encryption can no longer meet the growing demand for wireless security. On this basis, the physical layer security technology using the transmission characteristics of radio waves has ushered in great development, that is, through a certain transmission strategy, the useful signal rate of the signal received by the potential eavesdropping node is as low as possible fr...
