Embodiment Construction

[0071] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0072] Such as figure 1 Shown is a schematic diagram of the edge alliance and intra-alliance transactions of the present invention. exist figure 1 , depicts the service placement of an edge consortium consisting of two edge infrastructure providers (EIPs). In the figure, each edge node is associated with a base station, and users can access the network through the base station. Assume that the user has signed a relevant contract with EIP 1, that is to say, the user can only access the network through the base station of EIP 1. First, the user's service is placed on the edge node 1, then the user can access the service through the base station 1. As the price for accessing service...

Abstract

The invention discloses a service placement method for maximizing social welfare in an edge alliance, designs cooperation of the edge alliance in the horizontal direction, and integrates all edge nodes of all EIPs. Firstly, a service distribution problem is modeled into a planning problem for realizing social welfare maximization; then, the invention provides two EIP dynamic pricing methods so asto determine the bid for the client and the inner package price for other EIPs. Evaluation results based on two actual data sets show that the service placement model provided by the invention can enable the total gain of the EIP to be increased by 24.5% at most, and the total delay to be reduced by 35.5%.

Description

technical field [0001] The present invention relates to related fields such as mobile edge computing, the Internet of Things, economics and the like, and in particular to a method for service placement. Background technique [0002] In MEC, the user's service placement problem has been studied for many years. Some researchers use heuristic algorithms to solve the placement of K cloudlets and the assignment of users to cloudlets. However, this approach has no approximation to prove its effectiveness. To this end, a constant factor approximation algorithm is proposed to find feasible solutions to the service placement problem to maximize the total system reward. Considering the mobility of users in MEC, some studies have used predicted user mobility or future cost parameters to find the optimal service placement solution. In order to avoid the prediction of user movement, the long-term optimization problem can be decomposed into a series of time slot problems to solve the s...
