Embodiment Construction

[0045] The present invention will be further described below in conjunction with embodiment:

[0046] figure 1 The network includes four mobile users (or tasks, applications) S1, S2, S3 and S4, three wireless network access base stations B1, B2 and B3, and two edge cloud servers C1 and C2. Any user Si (i=1,...,4) computes the offload task by a quaternion portray; among them, Indicates the user Si task computing resource demand, and Denote the delay-energy weighted cost of user Si accessing B1, B2 and B3 respectively. For example, for users S1 and (2,3,2,5), the computing resource requirement for offloading computing tasks is 2 units, and the delay-energy weighted costs of accessing B1, B2, and B3 are 3, 2, and 5, respectively. . Any wireless network access point Bj (j=1, .., 3) consists of a two-tuple Depict, respectively represent the cost of wireless network access point Bj accessing edge cloud servers C1 and C2. For example, for wireless network access base sta...

Abstract

The invention discloses an unbalanced edge cloud network access and resource allocation mechanism based on fairness criteria, which belongs to the field of mobile cloud computing and mobile edge computing. The invention uses a loop algorithm to start each round of resource allocation cycle according to The defined uninstall priority parameter is used to determine the user who obtains the task migration right, and the user with the smallest uninstall priority parameter obtains the task migration right of the current round. After determining the user who has obtained the task migration right, VDC determines the migrated task and the migration path by calculating the total unloading delay-energy consumption-cost weight sum of all tasks of the user, and the total unloading delay-energy consumption-cost weight And the smallest tasks are migrated first. This loops until the algorithm ends. This method can realize multi-user multi-task offload decision-making and resource allocation in an unbalanced edge cloud network, and can ensure service fairness among users on the premise of significantly reducing the total delay-energy consumption-cost weight of multi-user multi-task offload.

Description

technical field [0001] The invention belongs to the field of mobile cloud computing and mobile edge computing, in particular to an unbalanced edge cloud network access and resource allocation mechanism based on a fairness criterion. Background technique [0002] In recent years, a new technology called Mobile Edge Computing (MEC, Mobile Edge Computing) has been proposed. In essence, mobile edge computing technology can be seen as an extension or expansion of mobile cloud computing technology to the edge of the network. In fact, the concept of MEC was first proposed by the European Telecommunications Standards Institute (ETSI, European Telecommunications Standards Institute) in 2014, which is defined as "providing IT and cloud A new platform for computing power". In this model, massive computing and storage resources are placed at the edge of the network, close to mobile devices or sensors. Therefore, mobile users can migrate computing-intensive tasks to the MEC server for...
