Embodiment Construction

[0038] The present invention is described in further detail below in conjunction with accompanying drawing:

[0039] Such as Figure 1 to Figure 4 As shown, a communication method based on named data network for urban Internet of Vehicles establishes multi-level data exchange nodes, the lowest-level data nodes in the multi-level data exchange nodes are connected to roadside units, and the communication range covered by an RSU is defined as a dynamic In the topology domain, the communication between vehicle nodes belonging to a dynamic topology domain is intra-domain communication, and the communication behavior between vehicle nodes under the jurisdiction of different RSUs is inter-domain communication. In an RSU domain, the communication radius of RSU is according to D 0 、D 1 、D 2 、D 3 …D i Carry out radius interval division, and these radius lengths correspond to area I respectively 0 , I 1 , I 2 , I 3 …I i , the location area closest to the RSU is I 0 ; There are...

Abstract

The invention discloses an urban Internet of Vehicles communication method based on a named data network. RSUs are introduced into a static backbone network as managers of local topology; establishinga multi-stage data exchange node; the lowest-level data node in the multiple levels of data exchange nodes is connected with a road side unit, the communication range covered by one road side unit isdefined as a dynamic topology domain, and a vehicle node initiating a data request is used for preferentially inquiring an FIB table of the road side unit of the area where the vehicle node is located to determine whether a known data request interface exists or not; judging whether the interest packet and the roadside node of the region where the interest packet is located meet information exchange requirements or not, and realizing intra-domain or inter-domain communication of the interest packet by utilizing a roadside unit until a data packet is returned or the life cycle of the interestpacket is ended; the purpose of controllability is achieved by dividing and reducing the dynamic network topology range, and an intra-domain layering and inter-domain grading communication mechanism is adopted, so that the communication resource utilization rate in the Internet of Vehicles is improved, the routing efficiency is improved, and the communication stability is improved.

Description

technical field [0001] The invention relates to the field of vehicle networking communication and named data network communication field, in particular to an urban vehicle network communication method based on named data network. Background technique [0002] As a new content-centric network architecture, named data networking has incomparable advantages in many aspects such as load balancing, redundancy reduction, and flexible expansion, which can effectively reduce the deployment difficulty of the Internet of Vehicles. However, in the real Internet of Vehicles environment, due to the characteristics of rapid network topology changes and high-speed vehicle movement, how to improve the communication efficiency of urban Internet of Vehicles based on named data networks is an urgent problem to be solved. Contents of the invention [0003] The purpose of the present invention is to provide a communication method for urban Internet of Vehicles based on a named data network, so...
