Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] A multi-factor decision routing protocol based on connectivity in VANET environment (The Multi-factorDecision Routing Protocol Based on Network Connectivity in VANET), its core idea is to use the principle of combining macro path selection mechanism and micro forwarding mechanism to realize the The reliable and effective transmission of packets makes the communication between vehicles in the transportation network more reliable, and the routing decision information during driving is more accurate. When a vehicle node and a target vehicle node in the network need to transmit data packets, the RSU-assisted macro path selection mechanism and the target node tracking mechanism are used to ensure the connectivity of the transmission path during the entire transmission process of the data packet, and the transmission is carried out on the established path. During unic...

Abstract

The invention relates to a multi-factor decision making route protocol based on connectivity in VANET, wherein the route protocol combines city VANET features with route protocol designing problems, and is suitable for the city scenes; each vehicle node in the multi-factor decision making route protocol is provided with a navigation positioning system and electronic map equipment, thus periodically obtaining self information, and obtaining RSU positions and a road topology structure in the same time; when the vehicle node in the network needs to send a data package to a target node, the target node real time information can be obtained through a position service feedback system, and added into a data package header. The multi-factor decision making route protocol can use the vehicle node and deployed roadside RSU information interaction and various types of V2R message statistics to obtain the vehicle distribution conditions on the road, thus calculating the road density, and using a principle ensuring the connectivity and short path priority to select the optimal path connecting the source node with the target node.

Description

technical field [0001] The invention relates to a connectivity-based multi-factor decision routing protocol (The Multi-factor Decision Routing Protocol Based on Network Connectivity in VANET, which is applicable to VANET in urban scenarios) in combination with the characteristics of urban VANET networks and the problems existing in the design of routing protocols. MDCR). Background technique [0002] In recent years, with the rapid development of automobile industry, electronic communication, computer and other fields, intelligent transportation system (Intelligent Transportation System, ITS) came into being. Vehicular Ad-Hoc Networks (VANET) is an important direction for the development of intelligent transportation in the future. It uses vehicles equipped with communication transmission modules and road infrastructure as nodes to realize vehicle-to-vehicle (V2V, Vehicle-to-vehicle) -Vehicle Communication) and information exchange between vehicles and road facilities (V2R,...
