Problems solved by technology

In this case, the system migration decision and resource allocation design need to jointly consider the delay-energy-cost trade-off; third, the existing methods are all centralized methods, and the method execution unit needs to collect a large amount of user task attribute data, information The interaction overhead is high, and the method converges slowly

Embodiment Construction

[0049] The present invention will be further described below in conjunction with embodiment:

[0050] 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 stat...

Abstract

The invention discloses a distributed unbalanced edge cloud network access and resource allocation method, belonging to the field of mobile cloud computing and mobile edge computing; in each round of resource allocation, multi-user and multi-task based on available wireless access base stations and the edge cloud server, send service requests to the wireless access base station and the edge cloud server on the optimal path; if the resource required by the service request of the edge cloud server exceeds the maximum available resource, the task is reserved and other user tasks are rejected; the edge cloud server Update the current service user task set according to the rejection information, and repeat the above steps based on the updated data for the rejected user tasks, until all user tasks have been uninstalled or all tasks have no access to wireless access base stations and edge cloud servers. The invention can significantly reduce the weighted sum of total time delay-energy consumption-cost of offloading of multi-user and multi-task.

Description

technical field [0001] The invention belongs to the field of mobile cloud computing and mobile edge computing, and in particular relates to a distributed unbalanced edge cloud network access and resource allocation method. Background technique [0002] Mobile Internet and mobile application innovation still face three major contradictions: 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 operators, but the pipeline of the operator's network is serious and the average revenue per user is constantly decreasing. In order to solve the above contradictions, a new technology of Mobile Edge Computing (MEC, Mobile Edge Computing) was proposed, which is defined as "a new technology that provides IT and cloud computing capabilities in a radio access netwo...
