Abstract

This disclosure describes a method for predicting a jamming attack on a wireless energy transfer communication network, including the base station performing channel estimation, calculating the first credible throughput and assigning a transmission time period to each user. The assignment result is notified to the user through broadcasting, and the attacker listens As a result of the allocation, the user with the longest transmission time period is taken as the target user, and the preset interference power is set based on the transmission time period of the target user. When the first credible throughput reaches the first threshold, the base station transmits energy to the user, and the user receives energy And transmit a data signal to the base station, when the target user transmits the data signal, the attacker transmits an interference signal, the base station calculates the security outage probability, the second credible throughput and the cost-performance ratio based on the received data signal, and compares the second credible throughput of the target user Signal throughput and the second threshold required by the system, and compare the cost-performance ratio of the target user with the third threshold to predict the attack, and only decode the received signal if both thresholds are satisfied.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to a method and system for predicting a blocking attack in a wireless energy transmission communication network. Background technique [0002] A wireless powered communication network (WPCN) is a communication network that obtains energy by collecting signals in the environment, and uses the obtained energy as an energy supply for a user terminal. A wireless power transmission communication network (WPCN) includes a base station and a user (that is, a user end). Each time a data signal transmission is completed between the base station and the user, it mainly includes four stages, namely, channel estimation, time allocation, energy transmission and information transmission. [0003] When there is an attacker in a wireless power transmission communication network (WPCN), the attack method of the attacker affects the final performance of the WPCN. In parti...
