Vehicle-mounted self-organization network performance analysis method based on millimeter waves

Abstract

The invention discloses a vehicle-mounted self-organization network performance analysis method based on millimeter waves. The method comprises steps of establishing a vehicle-mounted self-organization network based on millimeter waves, wherein vehicle nodes in the vehicle-mounted self-organization network based on millimeter waves are distributed in a unidirectional straight road, the arrival process meets the Homogeneous poisson process, the communication link is divided into a sighting distance link and a non-sighting distance link, and the channel fading meets the index distribution, and establishing an analysis model of a millimeter wave vehicle-networking self-organization network; according to the millimeter wave vehicle-networking self-organization network, calculating the networkcoverage probability, the transmission capacity, the region frequency spectrum frequency and the reachable speed coverage probability. Compared with the prior art, by comprehensively considering the effects of vehicle node space distribution, shade effects, channel shading and same-frequency interference effect factors in a wireless communication process, and fully using characteristics of narrowwave beams of millimeter waves and high directivity, the power of signals is improved and same frequency interference is inhibited; and an actual communication scene of the vehicle-networking self-organization network can be well reflected.

Description

technical field [0001] The invention belongs to the field of wireless communication, and more specifically relates to a method for analyzing the performance of a vehicle-mounted ad hoc network based on millimeter waves. Background technique [0002] The Internet of Vehicles can realize the sharing of road traffic conditions between vehicles, the exchange of vehicle driving and braking information, and further provide multimedia sharing and mobile network services by establishing networks in the form of people-to-vehicle, vehicle-to-vehicle, and vehicle-to-roadside units. and other functions. [0003] Early research on connected vehicle networks mainly focused on the relative position of vehicles. Usually only from a geometric point of view, it is simply considered that when the Euclidean distance of the vehicle is less than a certain threshold, the communication can be realized, and when the threshold is exceeded, the communication between the vehicles cannot be established...

AI Technical Summary

Problems solved by technology

There may be fading and shadowing effects in the channel, and there may be co-channel interference between vehicles communicating at the same time, so that the communication of vehicles is not only affected by the distance
