A vertical handover selection method for heterogeneous wireless Internet of Vehicles

Abstract

The invention discloses a heterogeneous wireless Internet-of-Vehicles vertical switching selection method, which comprises the steps of: dividing vehicles into groups through calculating a vertical switching tendency value of each vehicle, acquiring an objective function according to a grouping result and a load balancing factor; and acquiring an optimal solution through restraining the objective function to obtain a vertical switching selection result of each vehicle. The heterogeneous wireless Internet-of-Vehicles vertical switching selection method provided by the invention considers gain of user throughput capacity at the same time after switching, considers the situation of gain on the whole process of the business service by means of the part of throughput capacity, achieves full utilization of heterogeneous wireless Internet-of-Vehicles system resources, and enhances user experience.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a vertical switching selection technology for heterogeneous wireless Internet of Vehicles. Background technique [0002] With the wide application of various wireless communication technologies, more and more users begin to use heterogeneous wireless networks to improve service experience. The Internet of Vehicles system has used existing mature communication technologies for data transmission, including cellular mobile communication networks, wireless metropolitan area networks, wireless local area networks using roadside access points, and self-organizing networks formed by vehicles. Facing the vertical handover selection decision in heterogeneous networks, nodes in the traditional sense usually do not have high mobility like vehicle nodes. In the vertical handover selection decision, the algorithm considers the quality of the network channel, the ne...

Such a situation may result in that the wireless LAN system accepts a large number of vertical handover services, causing the system load to be too high, the ability to receive new services is greatly reduced, and user experience is degraded.

However, the cellular mobile communication system, whose system load is relatively low, because a large number of service objects are vertically switched into the wireless local area network, resulting in a further drop in load.

The result is that the cellular mobile communication system has a large amount of bandwidth resources and cannot be fully utilized, and the wireless LAN system affects user experience due to insufficient resources.
