Problems solved by technology

Most of the existing routing and forwarding protocols based on named data networks do not consider the division of message categories, the different requirements of different messages for transmission, and the influence of geographical location factors on message transmission. Therefore, when it is directly applied to the Internet of Vehicles, the efficiency of message transmission remains to be seen Further improve

Embodiment Construction

[0065] The present invention is described in further detail below in conjunction with accompanying drawing:

[0066] Such as figure 1 As shown, a hybrid routing and forwarding strategy for Internet of Vehicles based on named data network, the steps are as follows: each vehicle node in the Internet of Vehicles environment is equipped with at least one wireless communication interface, GPS positioning and electronic map, and has storage and computing capabilities, which can Obtain the location of the destination pointed in the Interest packet through GPS. This design involves three types of data packets: (1) Interest packet: when a node requests data, it will send an Interest packet, which records the name of the required data, (2) Data packet: if a node receives an Interest packet and has The corresponding data packet will reply to the Data packet, and return to the node that requested the data according to the forwarding path of the Interest packet. (3) Bancon packet: Bancon ...

Abstract

The invention discloses a vehicle networking hybrid route forwarding strategy based on named data network. In a vehicle networking environment, with multiple message types, including security messages, entertainment news, the public service message and the auxiliary driving message, taking into account geographic location information, the impact of message classification and the need for real-timemessaging on message delivery, messages are categorized into location-dependent and location-independent, each type of message contains an emergency message and a normal message, and different forwarding strategies are adopted to carry out adaptive forwarding, so as to realize fast and reliable forwarding of messages in vehicle networking environment, reduce transmission delay, reduce packet lossrate, thus providing technical guarantee for fast and reliable message forwarding in vehicle networking, and improve the forwarding efficiency of messages.

Description

technical field [0001] The invention relates to the technical field of data transmission of the Internet of Vehicles, in particular to a mixed routing and forwarding strategy of the Internet of Vehicles based on a named data network. Background technique [0002] In the traditional Internet of Vehicles, due to its own topology changes rapidly, vehicles are highly dynamic and other factors, the network is frequently disconnected, the communication is unstable, and the efficiency of message transmission is difficult to guarantee. Named Data Network (NDN) uses named data instead of IP addresses. It is a data-centric and content requester-driven new network architecture that can effectively solve the data communication brought about by mobility and intermittent connections in the Internet of Vehicles. Therefore, it is more suitable for the real-world application environment of the Internet of Vehicles. Most of the existing routing and forwarding protocols based on named data ne...
