Evaluation method for transmission performance of vehicle self-organizing network data

Abstract

The invention discloses an evaluation method for transmission performance of vehicle self-organizing network data, comprising the steps of firstly, the method designs unified self-organizing network communication environment of real vehicles and uses the current UDP communication mechanism to design test method under the real vehicle self-organizing network environment, afterwards, designing specific data processing method and evaluation standard based on features of vehicle self-organizing network and principle of statistics, thereby to be able to consider the complexity of vehicle self-organizing network under real data transmission environment. The invention designs evaluation method for transmission performance of vehicle self-organizing network under real vehicle environment on the basis of relevant statistical method, the method can take the features of vehicle self-organizing network into account and study the relationship between data transmission performance and external environment parameter so that to provide real data support for subsequent product development and network optimization etc.

Description

technical field [0001] The invention relates to a wireless network testing technology, in particular to a wireless network performance evaluation technology for vehicle ad hoc network communication, and belongs to the field of computer technology. Background technique [0002] Intelligent transportation technology plays an increasingly important role in modern transportation and has become the development direction of the future transportation system. Efficient wireless communication technology is the basis for realizing intelligent transportation technology. Therefore, the vehicle-mounted ad hoc network technology based on DSRC should be applied The Vehicular Ad Hoc Network (VANET) is a mobile ad hoc network that can communicate between vehicles on the road (V2V) and between vehicles and roadside access points (V2I). Vehicles on the road can exchange various data such as speed, location and on-board sensors, and automatically connect into a wireless distributed network with...

AI Technical Summary

Problems solved by technology

At present, the testing of DSRC equipment at home and abroad mainly focuses on physical layer testing and protocol conformance testing, etc., and the research on network performance is insufficient, and there is a lack of testing and evaluation methods for data transmission performance in real vehicle environments.
