Evolutionary game based mode selection and spectrum allocation mechanism in heterogeneous full-duplex D2D cellular network

Abstract

The invention discloses an evolutionary game based mode selection and spectrum allocation mechanism in a heterogeneous full-duplex D2D cellular network, and belongs to the field of cellular network optimization. In a full-duplex D2D cellular network, communication users are randomly distributed, the users can communicate with other communication devices at random, and communication spectrum is reasonably allocated, under the condition that the service quality of base station users and D2D users is guaranteed, the communication capacity of the network is maximized, and network congestion is reduced. According to the invention, the communication model of the heterogeneous full-duplex D2D cellular network is randomized and formulated. Firstly, the network as a whole is quantitatively distributed by use of random distribution, the communication performance of the communication users is analyzed by use of a cumulative distribution function, then the whole network is subjected to evolution analysis by use of an evolutionary game approach, the communication mode is selected, and finally, the overall throughput of the network is maximized.

Description

technical field [0001] The invention discloses that in the heterogeneous full-duplex D2D cellular network, base stations and users are randomly distributed in Poisson space in space, and users select communication modes based on evolutionary games, and the premise of ensuring the communication quality of users of macro base stations and small base stations Under this circumstance, multiplexing and dedicated spectrum allocation are carried out to achieve the purpose of optimizing network performance and improving network throughput, which belongs to the field of network optimization. Background technique [0002] With the rapid development of wireless communication technology, mobile communication transmission traffic has shown explosive growth. In the next generation wireless network, users hope to obtain high-speed and wide-coverage services. However, the macro base station communication mode has a large service range due to the small distribution density of base stations. ...

[0004] In traditional game theory, it is often assumed that the players in the game are completely rational and proceed under the condition of complete information. However, in terms of participants in real economic life, it is difficult to realize the complete rationality and complete information of the participants.
