Problems solved by technology

At present, there are few studies on the migration decision-making and resource allocation under this unbalanced mobile edge cloud server deployment; the system design objectives of the existing research on the migration decision-making and resource allocation of the mobile edge cloud computing system are mainly delay, energy consumption or time. The delay-energy weight sum does not consider the service (use) cost of the mobile edge cloud server

Embodiment Construction

[0039] The present invention will be further described below in conjunction with embodiment:

[0040] figure 1The 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 quadruple portray; among them, Indicates the user’s Si task computing resource demand, with 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 stati...

Abstract

The invention discloses a nonequilibrium edge cloud network access and resource allocation mechanism and belongs to the field of mobile cloud computing and mobile edge computing. According to the mechanism, through utilization of a round robin algorithm, in each resource allocation round robin, for multiuser multitasks, the optimum task unloading paths are independently selected according to the minimum delay-energy consumption-cost weighted sum criterion; and the tasks with the globally minimum delay-energy consumption-cost weighted sums obtain current edge cloud server and radio access basestation resource allocation authority. According to the method, multiuser multitask unloading decision and resource allocation in a nonequilibrium edge cloud network can be realized, and the multiusermultitask unloading total delay-energy consumption-cost weighted sums can be clearly reduced.

Description

technical field [0001] The invention belongs to the field of mobile cloud computing and mobile edge computing, and in particular relates to an unbalanced edge cloud network access and resource allocation mechanism. Background technique [0002] At present, mobile Internet and mobile application innovation still face three major contradictions, including: the demand for computing-intensive applications on mobile devices is increasing rapidly but the computing power and battery capacity of mobile devices are limited; the demand for mobile cloud access is increasing rapidly but the access capability is limited; There are more and more technological innovations, but the operator's network pipeline is serious and the average revenue of users is constantly decreasing. In order to solve the above contradictions, a new technology of Mobile Edge Computing (MEC, Mobile Edge Computing) has been proposed and has become one of the key network technologies of the fifth-generation mobile c...
