Brent delay optimization method for mobile edge computing based on non-orthogonal multiple access in multi-base station scenarios

The invention relates to a mobile edge computing Brent-type time delay optimization method based on non-orthogonal multiple access in a multi-base station scenario, comprising the following steps: (1)there is one mobile user in the coverage area of BSs of an integrated edge server, and the optimization problem is described as a multi-variable non-convex optimization problem; (2) decomposing the problem (DM i) into two levels of optimization problems; (3) According to the bottom DM-I-E-Sub problem, a split-search method based on Lagrange multiplier is proposed to optimize the overall delay ofmobile subscriber i under the condition of the transmission time ti of mobile subscriber i. (4) For top-level DM-I-E-Top problem, Brent method is proposed to optimize the transmission time ti of mobile subscriber i. (5) The problem (DM i) is solved by iteration of the bottom problem and the top problem. The invention improves the transmission efficiency of the system, saves bandwidth resources, and obtains higher quality w
