Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 2 As shown, the present invention is set in the communication sublayer of each communication terminal, which includes a message sending frequency adaptive module 1, a message compression assembly module 2, a message priority module 3 and a message adding and decrypting module 4.

[0024] The message sending frequency adaptive module 1 is used to receive the message sent from the upper layer application, judge whether the message is sent according to the sending result stored in the message, if sent, send it to the message compression assembly module 2, otherwise not send.

[0025] The message compression assembly module 2 includes an identification unit 21 and a message dictionary development library 22 . The identifying unit 21 is used to identify the fields in the message body and their corresponding values, and sequentially ...

Abstract

The invention relates to an adaptive communication system for safety information of the Internet of Vehicles, which is set in the communication sublayer of each communication terminal, and is characterized in that it includes a message sending frequency adaptive module, a message compression and assembly module, and a message priority module And the message encryption and decryption module, using each module to solve the problems that the communication service frequency in the Internet of Vehicles cannot be adjusted adaptively, the message transmission is redundant, and the problem of lack of a priority service mechanism is solved. In addition, a message encryption and decryption module is also provided, which encrypts the formed message to solve the problem of communication security. Therefore, the present invention can be widely used in the fields of traffic control and Internet of Things communication.

Description

technical field [0001] The invention relates to an adaptive communication system, in particular to an adaptive communication system for safety information of the Internet of Vehicles. Background technique [0002] The Internet of Things is the third wave of the world's information industry after the computer Internet and mobile communications, and the research on it from various countries is increasing day by day. Due to the rapid development of current wireless networking technology and vehicle technology and the actual needs, the Internet of Vehicles, which is most likely to be realized first in the Internet of Things, has become the key support and promotion field of the Internet of Things. As a wireless network, an important problem facing the Internet of Vehicles is the communication problem. At present, the communication quality of the Internet of Vehicles has a large room for improvement. [0003] In the initial stage of the development of the Internet of Vehicles, d...
