Abstract

The invention discloses a multi-access calculation shunting method with safety guarantee based on simulated annealing. The method comprises the following steps: (1) considering a certain mobile user i, within K base station service ranges, each base station is provided with an edge computing server which can provide computing offloading service for the mobile user i, and the uplink transmission total energy of the mobile user is minimized while the service quality of the mobile user is met and the transmission information security of the user is ensured; (2) decomposing the problem TECM into two layers of optimization problems; (3) aiming at a bottom layer problem, applying a Lagrangian constant method, carrying out linear enumeration on an overflow probability, and optimizing the total energy consumption of the system; (4) according to the top layer problem, adopting a simulated annealing algorithm, and further optimizing the total energy consumption of the system; and (5) through interactive iteration of the bottom-layer problem and the top-layer problem, finally solving the problem TECM. The safety and the reliability are relatively high.

Description

technical field [0001] The invention belongs to the communication field, and relates to a simulated annealing-based multi-access calculation distribution method with safety guarantee. Background technique [0002] The massive growth of global mobile data volume will bring huge challenges to future mobile users. The emergence of edge computing technology makes it possible for mobile users to offload computing, thereby reducing their own computing pressure. In order to realize data distribution, some mobile users are easy to be maliciously eavesdropped, which leads to security overflow problem. Contents of the invention [0003] In order to overcome the disadvantage of relatively large uplink transmission energy in the prior art and meet the security performance requirements of mobile users, the present invention provides a simulated annealing-based multiplexer with security guarantees that minimizes uplink transmission energy on the premise of meeting security performance ...
