Abstract

The invention relates to a resource allocation method for improving the safety performance of wireless transmission of the Internet of Vehicles, comprising: acquiring first communication parameters of each first communication link in the Internet of Vehicles, second communication parameters of each second communication link, first eavesdropping The first eavesdropping parameter of the link and the second eavesdropping parameter of the second eavesdropping link, and then calculate the first communication link and the second communication link on each resource block according to the first communication parameter and the second communication parameter respectively. Channel transmission capacity, calculate the first eavesdropping channel capacity and the second eavesdropping channel capacity according to the first eavesdropping parameter and the second eavesdropping parameter, and then determine the total security capacity of the system through the transmission capacity of each channel and the capacity of each eavesdropping channel, based on the total security capacity of the system The biggest goal is to establish a joint model of resource allocation and power control, and to allocate resource blocks, which can improve the security performance of the system by improving the security capacity of the system.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a resource allocation method for improving the safety performance of wireless transmission of the Internet of Vehicles. Background technique [0002] With the increasing requirements for data transmission security in wireless networks, information security has become a key issue. Different from the application of traditional cryptography in the upper layer of the network architecture, the physical layer security technology mainly studies how to use the characteristics of the physical layer channel in the wireless network to achieve secure communication in the absolute sense, that is, it can be used without high-level encryption or by eavesdroppers. can still provide effective confidential communications. [0003] State Grid Corporation of China put forward the vision of "smart vehicle networking". Through the data fusion of vehicles, piles and networks, it can rea...
