Data security shunt transmission method based on linear search

Abstract

A data security shunt transmission method based on linear search comprises the following steps of: (1) from the view of intelligent equipment SD in a wireless network, transmitting a part of data to abase station BS, and shunting the other part to a low power wireless access node AP, wherein there is also a situation that the data is eavesdropped by a hidden eavesdropper, and the optimization problem that minimizes the total system power consumption is described as a non-convex optimization problem in the case of ensuring data transmission requirements and safety overflow limit; (2) vertically resolving the TPM problem to a two-level optimization problem; (3) proposing a monotonically optimized power control method according to the underlying problem to optimize the transmission power ofSD; (4) proposing a linear search method for the top problem to further save energy and optimize the total consumed power of the system; and (5) finally solving the TPM problem through interactive iteration between the underlying problem and the top problem. The invention has relatively high security and reliability.

Description

technical field [0001] The invention belongs to the field of wireless networks, and relates to a linear search-based data security shunt transmission method. Background technique [0002] The massive growth of smart devices poses a huge challenge to future Internet of Things (IoT) systems. Today, in the process of developing towards 5G / LTE technology, cellular networks can already provide huge throughput and reliable connection performance for a large number of smart devices. In a wireless network system, some low-power wireless access nodes that work in unlicensed frequency bands for data offloading are easy to be maliciously eavesdropped, which leads to security overflow problems. Contents of the invention [0003] In order to overcome the deficiencies of the existing wireless network, which is easy to be maliciously eavesdropped, resulting in the problem of security overflow, low security and reliability, the present invention provides a wireless network that reduces t...
