Resource management method of vehicle ad hoc network based on fuzzy algorithm

Abstract

The invention discloses a vehicle ad hoc network resource management method based on a fuzzy algorithm. The method is mainly used for solving the problem in the prior art that the resource management efficiency is relatively low. The realization steps comprises that a roadside server carries out statistics to time stamps, source node IDs, resource serial numbers, resource information, resource request times A and resource downloading times B in a resource list; fuzzy processing is carried out to the A and the B; then the survival time of resources is obtained according to a centroid method; the resource list is updated in real time; when the survival time of one resource is reduced to 0, the resource is deleted from the resource list; when the resources in the server overflow, the resources of which survival time is in a set range are periodically discarded; and the resource list is updated timely. According to the method, the search time of the user node to the roadside server node is reduced; the resource discovering speed is improved; the timeliness is realized; the resource updating efficiency is improved in a limited memory; the user experience is effectively improved; and the method can be used for communication of a vehicle and the roadside server.

Description

technical field [0001] The invention belongs to the field of communication technology, and further relates to a method for implementing internal real-time resource management by roadside servers using fuzzy logic algorithms in the field of vehicle ad hoc networks, which can be used for communication between vehicles and roadside servers to realize internal resource management of roadside servers. Background technique [0002] At present, the self-organizing network of vehicles is a large-scale multi-application network. Vehicles usually form large-scale networks such as entire cities and expressways. Information, as well as management information such as road speed limit notices, green light optimal speed recommendations, etc. At present, the newly integrated resources such as local multimedia, business and other entertainment and service information have different requirements for communication quality of service (QOS) and resource management. However, due to the frequent ...

AI Technical Summary

Problems solved by technology

[0005] First of all, the resource discovery of this type of method is not time-sensitive and flexible;

[0006] Secondly, since the resource management is only updated according to the time sequence, the resource processing efficiency is low, and the user resource experience is not rich
