Stackelberg game-based resource allocation method

Abstract

The invention discloses a Stackelberg game-based resource allocation method. According to the method, the interference of a cellular and femtocell-coexisting and spectrum-shared two-layer network is analyzed and managed; graph theory knowledge and the game theory are adopted to allocate resources used by users in femtocells and a macro base station, so that the quality of services for the users can be ensured. The method includes the following steps that: a graph theory-based clustering algorithm clusters the femtocells and sequentially allocates channels for macro users, and then matches the macro users with femtocell clusters so as to realize channel sharing; and a femtocell transmission power and macro user access selection-combined Stackelberg game is established, and the expression of the transmission power of the femtocells when Nash equilibrium is achieved is derived, and appropriate access strategies are selected for the macro users according to the transmission power of the femtocells, and iteration is repeated until Stackelberg game equilibrium is achieved, and network resource allocation is updated according to strategies which are selected when the equilibrium is achieved.

Description

Technical field [0001] The invention belongs to the field of communication technology, and relates to a method for resource allocation based on the Stackelberg game. Background technique [0002] With the development of communication technology and the advent of the information age, people's reliance on and demand for communication and networks are increasing day by day. In order to meet the needs of users for multiple services, the existing wireless communication systems adopt inter-system fusion technology to make the systems complement each other and cooperate to provide users with various existing services. These wireless communication systems together form a heterogeneous network. With the further development of heterogeneous network technologies, technologies such as wireless relay, small cells, and home base stations have emerged one after another. Among them, femtocells are also known as home base stations, which have the characteristics of low cost, green environmental ...

AI Technical Summary

Problems solved by technology

However, the introduced femtocell network usually uses the same spectrum as the macro cell to improve spectrum utilization, which introduces cross-layer interference between the two layers of networks, which often leads to degradation of user performance. Therefore, it is necessary to reduce interference through resource allocation.
