Embodiment 1

[0066] This experiment uses the MATLAB platform to test the algorithm AODV-MEC we set. Compare it with traditional AODV routing protocol, DSR routing protocol, GA-BFODSR routing protocol and AODV-EO routing protocol. For vehicle nodes at different driving speeds, different data packet sending rates, and different vehicle node numbers, the delivery rate of data packets between vehicle nodes, the average end-to-end delay between nodes and the overall routing The topology overhead control in the process is analyzed.

[0067] See attached Figure 7 , a clustered AODV routing method based on an edge computing strategy provided in this embodiment mainly includes the following key steps:

[0068] 1. Description of the basic principles;

[0069] 1.1. Establish road model;

[0070] We consider a two-way road with total length L ROAD , the vehicle moves at a constant speed on the road, and within the communication range, the vehicle density is ρ. There are roadside equipment RSUs ...

Abstract

A clustered AODV routing method based on edge computing strategy. Compared with the traditional mobile ad hoc network, this method has higher challenges in link stability and network topology control overhead due to the particularity of high-speed movement of vehicle nodes. In the traditional AODV routing protocol, the method of the present invention comprehensively considers the information of vehicle node energy and vehicle speed, optimizes the AODV routing protocol based on the minimum number of hops, and combines vehicle-to-vehicle and vehicle-to-road communication modes, By adding an edge server in the roadside unit RSU, a hierarchical clustering method is used, that is, the vehicle nodes in the cluster use the V2V communication mode, and the vehicle nodes between the clusters use the communication mode combining V2V and V2R to select the route. This method improves the efficiency of route selection in the ad hoc network of high-speed moving vehicles, and reduces the network topology control overhead caused by link disconnection and re-establishment due to high-speed movement.

Description

【Technical field】 [0001] The invention belongs to the field of the Internet of Things, and in particular relates to a clustered AODV routing method based on an edge computing strategy. 【Background technique】 [0002] With the popularity of mobile ad hoc networks and the rapid development of vehicles, the construction of intelligent transportation has become the general trend, and the mobile Internet of Things represented by vehicle ad hoc networks has also been derived. The Internet of Vehicles is an intelligent vehicle interconnection network in which the vehicle communicates with the surroundings in a relatively intelligent way according to a given communication protocol and data interaction standard. For traditional vehicle technology, in the Internet of Vehicles, the integration of modern communication and network technology is particularly important. The use of smart cars in the Internet of Vehicles environment brings great convenience to intelligent transportation, suc...
