Multi-target-network power distribution method in heterogeneous wireless network cooperative communication

Abstract

The invention discloses a multi-target-network power distribution method in heterogeneous wireless network cooperative communication. The multi-target-network power distribution method comprises the following steps that firstly, a mobile intelligent terminable detects wireless networks which are capable of being accessed and provided with vacant service channels, N wireless networks with good channel conditions are selected by the mobile intelligent terminal from the networks which are capable of being accessed, and the mobile intelligent terminal has access to the N wireless networks; secondly, a heredity expression of a power distribution scheme is defined; thirdly, an adaptation function of the power distribution scheme is defined; fourthly, M arrays are generated; fifthly, according to the method that a high-fitness value is preferential, genetic recombination is conducted through m2 genes randomly selected from a population; sixthly, mutation is conducted on m1 genes randomly selected from low-fitness genes of a population generated after genetic recombination according to the probability; seventhly, a new generation of population is selected and generated; eighthly, the fifth step, the sixth step and the seventh step are executed repeatedly, and when increase of the highest-fitness value of the population genes is smaller than a given threshold value successive l times and continuously, the optimal power distribution scheme is obtained. The multi-target-network power distribution method in heterogeneous wireless network cooperative communication has the advantages of being flexible in algorithm.

Description

technical field [0001] The invention relates to a wireless communication technology, 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 coexist widely, and no less than 25 kinds of heterogeneous wireless networks have been put into commercial use. However, each network works independently, and seamless interconnection between networks and full utilization of network resources have become major issues. 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 networks, collaborative work and seamless interconnection between networks, so that terminals can use multiple different types of networks for data ...

Problems solved by technology

[0005] Since networks of various standards, various types of services, and various quality of service (QoS) requirements are involved, the power allocation of heterogeneous wireless network cooperative communication systems requires multiple performance indicators as optimization targets (and these The optimization objectives often conflict with each other), and the existing power allocation method mainly aimed at a single standard network, a single type of business, and a single performance index as the optimization goal is no longer applicable
