Embodiment Construction

[0038] In order to express the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation cases.

[0039] figure 1 The system model block diagram used in the present invention specifically includes:

[0040] Since computing, communication, storage, and control resources are distributed in the core cloud, MEC server, and vehicle terminal, the resources are also distributed on all nodes under this architecture. Due to the heterogeneity of nodes, the storage, computing and network functions are also different. Therefore, these nodes should cooperate with each other to make full use of resources and improve data sharing performance; it is also necessary to cooperate in the heterogeneous Internet of Vehicles to optimally select different offloading modes. To achieve efficient collaboration and content sharing, the proposed...

Abstract

The invention researches a problem of making a related task uninstalling decision due to limitation of own resources after a vehicle releases an application demand. Due to an increasingly complex userrequest, the user request is partitioned into a plurality of fine granulated tasks, each task depend on each other, the tasks can be distributively uninstalled to an MEC server around to carry out computing, results are transmitted back after computing is ended, and task vehicles with small computation quantities can be locally executed after computation. MEC is scheduled by a core controller toimplement content sharing. The vehicles have movability and are changed along with an Ad hoc network topological structure, and thus, the invention firstly discloses a system framework, then disclosesa multi-node multi-factor cooperation scheme based on the framework and finally, discloses a resource cooperative scheduling mechanism by the means of a game theory for making a dispersion and entirety combined uninstalling decision, so that a task uninstalling delay is reduced, and a task execution rate is improved.

Description

technical field [0001] The invention relates to the technical field of wireless short-distance communication in the Internet of Vehicles system, and in particular to a distributed unloading and cooperative execution scheme of tasks based on MEC in the Internet of Vehicles system. Background technique [0002] Mobile devices are becoming more and more popular. The Cisco Visual Networking Index—Global Mobile Data Traffic Forecast, updated on February 3, 2016, indicates that monthly global mobile data traffic will reach 30.6 exabytes by 2020, up from 3.7 exabytes per month at the end of 2015. By 2020, it will become 50 billion connected devices, contributing to the good wishes of the Internet of Things. However, this unparalleled growth has not been matched by improvements in mobile device batteries, whose lifespan has not improved at the same rate. Addressing energy barriers is one of the top challenges facing the mobile industry given the massive increase in mobile device u...
