Embodiment Construction

[0067] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0068] In the existing technology, the communication cost is composed of two parts: one is the time delay for users to access the server to obtain calculation results, and the other is the energy consumed by users sending calculation tasks through channels.

[0069] Latency consists of three parts:

[0070] L=Δ t1 +Δ exe +Δ t2

[0071] Among them, Δ t1 is the necessary sending delay for sending computing tasks to the server. Δ exe is the runtime delay of computing tasks running on the server. Δ t2 is the reception delay for the calculation result to be returned to the user through the network. The receiving delay is generally irrelevant to the user's parameters, so it can be considered that all users receive the same delay. For easy calculation, the present invention saves the receiving delay, and the user's delay is: L=Δ t1 +Δ exe .

Abstract

The invention discloses an MEC server selection algorithm based on fairness, and belongs to the field of mobile communication. The algorithm comprises the steps of establishing a system model among users, channels and MEC servers; randomly selecting the users to be connected with the MEC servers by an initial system; sending calculation tasks in time t by the selected users, and matching the MEC servers for the users according to communication cost; uploading the calculation tasks by the users, and calculating the throughput of each user; sorting the throughput of all users in a descending mode, selecting former N users with the low throughput, and calculating the communication cost of the users; and for the users with the low throughput, selecting the MEC serves by the users for next time calculation. The algorithm has the advantages that the influences of delay and energy consumption on selection of the users to the MEC servers are taken into combined consideration, and a communication model is introduced into the system; and when the users are in different application scenes, different weight parameters are selected, the communication cost is controlled, and the algorithm has better scene adaptability.

Description

technical field [0001] The invention belongs to the field of mobile communication, and describes a fairness-based MEC server selection algorithm. Background technique [0002] Since the 21st century, with the development trend of modernization, informatization, digitalization and intelligentization, people's lives have been profoundly changed. In 2008, the concept of cloud computing began to attract widespread attention from the Internet industry, because cloud computing is inseparable from the network, "cloud" usually means the Internet, and cloud computing is to provide computing power through the Internet to fulfill certain needs of users. [0003] With the rapid development of the semiconductor industry and information technology, the functions of mobile terminals represented by smart phones are becoming more and more powerful and more and more popular. A large number of smart terminals have begun to access the network. At the same time, there are more and more types of...
