Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] The multi-access selection decision method of cognitive wireless network establishes a modular framework, and implements solutions according to the throughput, delay and reliability indicators of each module, such as figure 2 shown. Finally, multi-objective fuzzy decision-making considers user preferences, and uses the least square method to compromise the subjective and objective weights, which improves the problem of too much subjectivity in the traditional multi-access selection decision-making method, such as image 3 . First, the radio link module provides measurements of the throughput, latency, and reliability parameters of the wireless link behavior for ongoing communications; the transport layer module measures its perceived performance at the end-to-end network layer, i.e., throughput, latency, and reliability performance indicators; calculate the c...

Abstract

The invention discloses a decision-making method for multi-radio access selection of a cognitive radio network. Based on frame modularization, the method comprises the step that firstly a sharable knowledge base containing the service quality information of current and past active links is generated according to handling capacity indexes, delay indexes and reliability indexes which are independent in technology in the cognitive radio network. Fuzzy logical deduction and fuzzy mathematics are used in the process. The optimal target network is obtained by using a multi-objective fuzzy decision-making method on the basis that user preference indexes are taken into consideration. The decision-making method for the multi-radio access selection of the cognitive radio network has the advantages of proposing a solution of the multi-radio access selection with universality and structured characteristics aiming at the problem that a network multi-radio access selection solution cannot be widely applied to various wireless technologies. Due to the fact that accurate description and processing are carried out on fuzzy objects by fuzzy logic, accurate using of information can be further improved.

Description

technical field [0001] The invention relates to wireless network access technology, in particular to a cognitive wireless network multi-access selection method based on multi-objective fuzzy decision-making. Background technique [0002] The development of radio communication provides many network access technologies for wireless connection, such as IEEE802.11, WiMAX and UMTS. At the same time, advances in microelectronics research have allowed these technologies to be used on a single mobile device equipped with many radio interfaces. In the study of telecommunication, the topic of wireless network access selection has been widely concerned. In the case of many access point options, how to allow users to choose an optimal option that meets their needs. [0003] Most previous work dealing with this problem only considers a specific wireless technology. The most obvious example is 802.11: many valuable solutions have been proposed to solve the problem of access point selec...
