A multi-objective network power allocation method in cooperative communication of heterogeneous wireless networks

Abstract

The invention discloses a multi-target network power distribution method in heterogeneous wireless network cooperative communication. The method adopts a design structure with two-parent four-path parallel operation, and aims at providing a simple, efficient, scientific and reasonable multi-target network power distribution scheme for cooperative networks in heterogeneous wireless network cooperative communication; the optimization objective of the power distribution scheme is to maximize the transmission speed of intelligent module terminals and minimize the power consumption of the same, thus the performance of the intelligent mobile terminal in transmission speed and power consumption is simultaneously optimized, and the efficiency in a power distribution process is improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a multi-target network power allocation method in cooperative communication of heterogeneous wireless networks. Background technique [0002] At present, various heterogeneous wireless communication networks widely coexist, but each network operates independently, which makes the seamless interconnection between different networks and the full utilization of network resources very difficult. As a solution to this problem, heterogeneous wireless network cooperative communication technology has been highly valued at home and abroad. Heterogeneous wireless network cooperative communication technology can realize integrated access between heterogeneous wireless networks, collaborative work and seamless interconnection between networks, so that terminals can use multiple different types of wireless networks for data transmission at the same time, thereby significantly i...

The publication number is CN102752840A, and the invention patent "a broadcast channel transmission power allocation method" published on October 24, 2012 provides a method based on the gain signal-to-noise ratio of each channel and the weight value of each receiving end. Although the method of allocating transmission power at the receiving end reduces the complexity of the algorithm because there is no need to solve the water injection power level and iterative calculation process, the invention is aimed at a homogeneous network of a single standard, and only maximizes the system throughput as the optimization goal. Does not take into account the optimization of power consumption

The publication number is CN103561457A, and the publication date is February 5, 2014. The invention patent "a multi-objective network power allocation method in heterogeneous wireless network cooperative communication" uses genetic algorithm for power allocation. Although the invention jointly optimizes power and channel capacity, but the defects of genetic computing itself that are prone to "premature" in the early stage and slow evolution in the later stage have not been avoided. The adaptive mutation method adopted suppresses the diversity of individuals in the population, and the fitness function cannot balance the coordination power and channel capacity. The magnitude makes it very difficult to select the weight
