Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] The schematic diagram of mobile network-aware cloud network is as follows: figure 1 shown. The flowchart of the method of the present invention is as figure 1 shown, including the following steps:

[0042] Step 1: Establish a system model, that is, an abstract model of the cloud network.

[0043] The user's application runs on a dedicated cluster with compute nodes connected to the switch, thus abstracting the virtual network into a virtual cluster. A virtual network can be described by a topology: there are N servers in the cloud, and server n uses a bilateral communication link at a data transmission rate of B n Connect to a virtual switch, the virtual switch has a bandwidth

[0044] The computing resources of the cloud network can be represented by the following formula:

[0045] Θ cr,c =[Θ ct,c ,Θ cs,c ,Θ ms,c ,Θ ss,c ,Θ os,c ] ...

Abstract

The invention relates to a computing and wireless resource cooperative dispatching method in mobile cloud video transmission. The method comprises the steps that a system model, namely a cloud network abstract model is established; a video distortion model is established, an optimization target is provided; a random Restless Bandit system is established; and cloud service selecting and bandwidth distributing are carried out. The problem that in the prior art, system performance can be severely affected through respective and independent cloud and mobile resource management is solved, by combining a dynamic cloud network and wireless resource management, the end-to-end performance suitable for video transmission in a mobile cloud network computing system is improved, important video application layer parameters, namely the frame inner refresh rate are perfected, program quality is evaluated through distortion magnitude, and video distortion-preventing performance is improved.

Description

technical field [0001] The invention belongs to the related field of cloud and mobile resource management in wireless communication, and relates to a calculation and wireless resource cooperative scheduling method in mobile cloud video transmission. technical background [0002] At present, a lot of work is focused on network / service structure, resource timing, energy efficiency, and security, ignoring the comprehensive consideration of user services, mobile networks, and cloud servers. In the context of mobile cloud networks, in order to meet the quality of service required by various users, it is very necessary to manage computing / communication resources in heterogeneous clouds and wireless resources in mobile access networks. In the mobile cloud computing system, both the mobile access network and the cloud computing network are heterogeneous, which means that they have different kinds of hardware, software and structures, and resources, etc. [0003] In order to provide...
