Double-layer heterogeneous network power control method

Abstract

The invention discloses a double-layer heterogeneous network power control method. The method comprises the following steps: establishing a double-layer heterogeneous network power control model; initializing star positions and quantum positions and sorting the star positions and the quantum positions; selecting a new galaxy according to a tournament selection mechanism; updating a quantum rotation angle according to the chaos change of the position, and using a simulated quantum rotation door to evolve an optimization searching process of a galaxy; if the maximum cycle index is not reached, returning to the previous step until the maximum cycle index is reached, otherwise, terminating the cycle, performing positive and negative rotation chaotic movement on the star, and searching a better galaxis; if judging that the maximum number of cycles is not reached, returning to the previous step; otherwise, stopping the circulation, mixing the newly obtained galaxy with the initial galaxy, and selecting a galaxy with the same scale as the initial galaxy; if judging that the maximum number of iterations is not reached, returning to select a new galaxis according to the tournament selection mechanism; otherwise, stopping iteration to acquire an optimal power distribution scheme. The system throughput and the system energy consumption which conflict with each other can be optimized at the same time.

Description

technical field [0001] The invention belongs to the field of resource management, and relates to a power control method for a two-layer heterogeneous network, in particular to a multi-objective power control method for a two-layer heterogeneous network based on a multi-objective quantum galaxy search mechanism. Background technique [0002] With the advancement of communication technology, it can be seen that the communication between people has become more and more convenient. From hundreds of years ago, it was only possible to pass messages by flying pigeons and beating drums and beating gold, to later mailing letters or sending telegrams. To achieve mutual communication, up to now, only a phone call and a text message are needed to achieve the purpose of delivering messages, and even the requirements of meeting people can be realized through video and other methods. These progresses in communication are clearly visible to us, and at the same time, the requirements of users...

Problems solved by technology

However, the mechanism is too complicated, and the optimization effect is not obvious. Using the multi-objective quantum galaxy search mechanism, a power control method that is more robust and suitable for various situations can be obtained.

[0006] The search results of the existing literature show that most of the existing multi-objective power control methods convert the system throughput and energy consumption into a single-objective problem under a certain linear weight, but in actual situations, in order to improve the quality of user communication , it is necessary to increase the system throughput and increase the transmission power of the equipment according to various communication requirements, but the increase of the transmission power of the equipment will increase the energy consumption, which is not expected to be seen, so there is a lack of a system throughput and system Energy consumption is used as an objective function for multi-objective optimization. Therefore, it is urgent to solve the high-dimensional optimization problem of power allocation in two-layer heterogeneous networks, and to obtain a feasible power allocation scheme under any energy consumption and throughput requirements.
