Abstract

The invention discloses a distributed service matching sequential spectrum access decision-making method, comprising the following steps: acquiring a target system and initializing and defining the target system; calculating the expected throughput of the user's sequential detection order; based on the user's The expected throughput of the sequential detection order updates the user's own sequential detection order; based on the updated decision, the user selects the corresponding sequential detection order for channel sensing, accesses an idle channel, and transmits data. The present invention adopts a system optimization method for distributed learning based on the heterogeneous characteristics of distributed user business data, introduces an appropriate local cooperation mechanism in the channel access method, and proposes a service-driven local cooperative distributed learning algorithm, using local The small cost of information interaction gradually converges to the global optimal state, which realizes the optimization of the throughput of the network system.

Description

technical field [0001] The invention relates to the technical field of ad hoc wireless communication network access, in particular to a decision-making method for distributed service matching sequential spectrum access. Background technique [0002] At present, the 5G network is facing a serious shortage of spectrum resources, and the opportunistic spectrum access technology based on cognitive radio can effectively utilize idle spectrum resources. Cognitive radio technology is used in the research of microcellular network, which is called cognitive small cell network (Cognitive Small Cell, CSC). Cognitive microcells have the ability of cognitive radio to detect the radio environment, discover available idle spectrum channel resources, and dynamically adjust access parameters. Cognitive micro cells use opportunistic spectrum access technology to dynamically access better spectrum according to environmental conditions to provide business transmission services for their termin...
