Embodiment Construction

[0026] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The existing service selection method is not suitable for the edge computing environment. After research, it is found that, on the one hand, because the cloud server is powerful, it can satisfy all the functions requested by users by default, and there is no need to transfer service requests to other servers; on the other hand, in the traditional In the fixed network environment, during the service call process, the data transmission rate is relatively stable, and the geographical location where the user uploads the service input parameters and receives the service execution results is consistent. Compared with the traditional fixed network environment, the edge server has limited functions and cannot meet all service requests, and needs to transfer...

Abstract

The invention discloses a service selection method oriented to a mobile edge computing environment. The method comprises the following steps: (1) collecting all equipment information, service information and connection information between equipment in a system; (2) receiving a service request; (3) selecting a service for the service request by using a GAMEC algorithm; and (4) computing a destination edge server according to a service selection scheme and a user path. Compared with the prior art, the service selection method has the advantages that the location movement of a user in a service selection process is considered, and movement information of the user is fused into the service selection, so that the overall response time of the service is reduced through the service selection. Moreover, a selection scheme of the destination edge server is proposed, thereby further reducing the service response time. Moreover, a temperature control mechanism of a simulated annealing method is introduced into a genetic algorithm, so that the searching range of the algorithm can be enlarged at the initial stage of the algorithm; local optimum is avoided effectively; the convergence speed is increased at the termination stage of the algorithm; and the efficiency of the algorithm is increased.

Description

technical field [0001] The invention belongs to the technical field of software optimization, and in particular relates to a service selection method for a mobile edge computing environment. Background technique [0002] With the development of mobile devices and mobile communication technologies, mobile devices are becoming more and more popular, bringing great convenience to our work, life and study. At the same time, increasingly complex and diverse mobile applications also put forward higher and higher requirements on the computing, communication and storage capabilities of mobile devices, and these applications often exceed the capabilities of mobile devices. In order to meet these demands, mobile edge computing was proposed. Mobile edge computing aims to provide services for mobile devices on the edge devices of the network, so as to expand the capabilities of mobile devices. Edge devices refer to devices such as routers, switches, and base stations at the edge of the...
