Problems solved by technology

[0003] In view of the NP-hard characteristics of the hybrid collaborative content deployment optimization problem, the traditional approximate solution mainly converts the content deployment optimization problem into a monotone submodular function optimization problem constrained by a matroid, and then uses the greedy algorithm to solve it, in order to ensure a lower complexity at the expense of solution quality

Abstract

The invention discloses a cooperative caching method based on a brainstorming optimization algorithm in a fog wireless access network, comprising: (1) constructing an evaluation function based on a hybrid cooperative deployment optimization problem; (2) calculating the evaluation value of each decision variable, according to The evaluation value is used to classify the decision variables; (3) new decision variables are generated based on the classified decision variables of the previous generation; (4) corresponding caching decisions are made according to the caching decision variables with the highest evaluation values. The invention designs a hybrid cooperative caching method based on a brainstorming optimization algorithm, which can obtain a solution with better performance within an acceptable complexity range, and can effectively reduce the user request delay; its distributed computing characteristics are in line with fog wireless access. The network architecture is more suitable than the traditional centralized parsing algorithm.

Description

Technical field [0001] The present invention relates to a radio access network mist brainstorming cooperative caching optimization algorithm, the cache belongs to the technical field of mobile communications. Background technique [0002] Fog new radio access network architecture as the mobile communication system, the transmission cache popular content in the fog wireless access node, effectively reducing the user request delay. However, the limited storage space of the wireless access node fog, popularity of content distributed over the area coverage radio access node mist more dispersed, the edge cache greatly limits performance gain. In response to these problems, considering the cooperation between the vertical level of collaboration between the mist and fog wireless access node and a wireless access node center of the cloud, mist mixed cooperative caching mode in the radio access network to establish a more efficient use of limited of storage space. [0003] NP-hard in view...
