A multi-user computing migration method based on multi-radio communication

Abstract

The invention belongs to the field of mobile cloud computing, and particularly relates to a multi-user computing migration method based on multi-radio frequency communication. The method comprises thefollowing steps: a controller models the multi-radio frequency multi-user computing migration problem by using a multi-radio frequency multi-user computing migration modeling method based on parameter analysis according to the collected information of all users and the target of the system, and obtains an initial problem model Theta; According to the characteristics of the initial problem model Theta obtained in the previous step, the controller relaxes and transforms the model by using the relaxation and linearization method based on McCormick envelope, and obtains the relaxed problem modelTheta *. The controller uses branch-and-bound method to solve the relaxed problem model Theta obtained in the previous step, which maximizes the total number of beneficiaries and reduces the cost of user migration. The method of the invention simultaneously considers the calculation time delay and the calculation energy problem of the user, can meet the diversity of the user requirements, has highdata transmission rate of the user, and greatly improves the utilization efficiency of the multi-radio frequency.

Description

technical field [0001] The invention belongs to the field of mobile cloud computing, and in particular relates to a multi-user computing migration method based on multi-radio communication. Background technique [0002] With the popularity of smart phones, more and more mobile phone applications have appeared, such as: voice recognition, face recognition, augmented reality, etc. These applications all need to consume a large amount of resources, including mobile phone computing resources (CPU) and mobile phone power, and the characteristics of the small size of the mobile phone itself determine that the computing resources and battery power of the mobile phone are very limited. Therefore, the shortage of mobile phone resources and the excessive demand for application resources pose a huge challenge to the development of future mobile phone platforms. Computational migration is an emerging technology to address the above problems. It solves the problem of insufficient mobil...

Problems solved by technology

[0005] (1) Only a single user is considered in multi-radio communication, and resource competition among users is not considered

[0006] (2) Only single-channel communication and multi-channel communication are considered in multi-user communication, but the use of multiple radio frequencies for communication is not considered

The transmission resources of multiple frequency bands are not fully utilized, and multiple channels cannot be used for transmission at the same time
