Method for constructing vector space model for cognitive network resources

Abstract

The invention discloses a method for constructing a vector space model for cognitive network resources, which belongs to the technical field of wireless communication networks and mainly solves the problem that the prior art lacks in specific network resource models and unified standard for managing cognitive network resources. The method comprises the following steps: defining resources, resource elements and characteristic parameters of a cognitive network; dividing cognitive wireless communication network resources into four independent resource elements; defining the respective characteristic parameter for each resource element; constructing a coordinate system by utilizing the characteristic parameters corresponding to the resource elements, and respectively describing each resource element by using a mathematical space model; and constructing the mathematical space model by using the resource elements as coordinate axes, and describing the complete cognitive network resources. The invention enables the construction and structures of the cognitive network resources to be clear and vivid, provides convenience for management and distribution of the cognitive network resources, and can provide support and assistance for technology research and resource management in the field of cognitive network communication.

Description

Technical field [0001] The invention belongs to the technical field of wireless communication networks, relates to a method for resource modeling and characterization of a cognitive wireless communication network, and can be used for analysis and specific management of resources of a cognitive wireless communication network. Background technique [0002] Cognitive radio technology is an emerging communication technology that efficiently utilizes the frequency spectrum. The cognitive radio system obtains the usage status of the spectrum by sensing and detecting the spectrum environment. After analyzing the learning mechanism, it manages and allocates the remaining usable parts of the spectrum to meet the spectrum requirements of more services. [0003] Cognitive wireless network is a further technical field developed on the basis of cognitive radio. It believes that the network system has a cognitive process that can distinguish the current network status, and plan, make decisions ...

Problems solved by technology

For example, in the article "Resource Modeling for a Joint Resource Management in Cognitive Radio" by Vuk Marojevic, a system model for the four environments of spectrum, computing, user request and wireless request is established, but these model individuals are not considered comprehensively, and the involved resources cannot meet the end-to-end service requirements of network communication

In the research project "COGNEC: Cognitive and Opportunistic Wireless Communication Networks" of Oulu University, the resources of the cognitive network are simply classified to form wireless resources and other resources. On the basis of cognitive radio spectrum resources, it is pointed out that other expanded resources include Built-in Resources, User-interface Resources, Network Resources, Social Resources, etc., but only briefly list and explain these resources, neither give a specific resource model, nor define and express cognitive network resources, The management of cognitive network resources lacks unified norms and standards, and cannot provide a basis for the management and analysis of cognitive network resources
