Embodiment Construction

[0039] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0040] The present invention proposes a three-dimensional D2D matching algorithm based on a software-defined wireless network (SDWN). Under the SDWN architecture where the software-defined network and wireless network are integrated, the controller can perceive the device cache information in the global network to centralize the user Control to realize D2D full-duplex communication. The present invention utilizes a DAC (D2D-aware caching) cache strategy and the characteristics of full-duplex D2D, and realizes the maximum transmission rate of D2D users in the entire network by establishing a mixed integer programming problem. Firstly, aiming at the problem of lower transmission rate caused by full-duplex D2D users sharing CUE user spectrum resources, a power control algorithm with low complexity and fast operation speed is applied; then, based on...

Abstract

The invention provides a three-dimensional D2D matching algorithm based on a software-defined wireless network (SDWN), and the algorithm comprises the steps: carrying out the centralized control of auser through the perception of equipment cache information in a global network through a controller under the architecture of the fusion of the software-defined network and the wireless network, and achieves the D2D full duplex communication. According to the invention, the DAC (D2D-aware cache) caching strategy and the full duplex D2D characteristics are utilized, and the whole network D2D user transmission rate maximization is realized by establishing a mixed integer programming problem. According to the algorithm, a power control algorithm with low complexity and high operation speed is applied to solve the problem that the transmission rate is reduced due to the fact that full duplex D2D users share CUE user spectrum resources; and on the basis of the graph theory model, a three-dimensional matching algorithm is constructed to carry out D2D full duplex matching and multiplexing channel distribution, and one-to-one matching is realized. The algorithm is different from an existing price-based three-dimensional matching algorithm, the algorithm complexity is low, and the implementation effect is slightly good.

Description

technical field [0001] The invention belongs to a three-dimensional D2D matching algorithm of joint power control under a software-defined wireless network architecture, relates to an SDWN architecture, a DAC cache strategy, and solving mixed integer programming problems, and is embodied in a power control algorithm and a three-dimensional matching algorithm based on a hypergraph model. Background technique [0002] Software-defined networking (SDN) is a software-based networking technology that advocates the separation of control and data. The software-defined network architecture divides the network into an application layer, a control layer, and a data layer. The application layer provides an open programming interface and network view to the control layer through the northbound interface. The control layer includes the controller and network operating system, and controls the data layer through the southbound interface for data processing, forwarding and collection. The...
