Distributed wireless network wireless resource distribution method

Abstract

The invention provides a distributed wireless network wireless resource distribution method, which belongs to a distribution method carrying out resource distribution according to the distributed wireless network wireless terminal volume, the resource finiteness and the quality condition of the signal channel conditions. The invention is established on a Stackelberg game model of a source node and a cooperative relay node, respectively provides respective network effectiveness functions of the source node and the cooperative relay node, and carries out the resource distribution behavior game according to the quality condition of the signal channel conditions. The method of the invention is suitable for a mobile terminal system with limited energy in Ad Hoc Network. The invention reduces the power cooperation of the cooperative node with poor signal channel condition, saves the energy consumption, does not influence the effectiveness of the system, and adopts the effective service amount of the transmission as the source node benefits. Compared with a method of adopting achievable rate as the benefits, the invention conforms to the valuable significance, and adapts to the variable signal channel state.

Description

technical field [0001] The invention belongs to the technical field of wireless network communication, and in particular relates to a distributed wireless network wireless resource allocation method. Background technique [0002] As a method to effectively resist multipath fading of wireless channels and improve network coverage, cooperative diversity has attracted extensive attention in the industry in recent years. Multiple independent terminal devices cooperate with each other to form a virtual antenna array, thereby improving the overall performance of the system. Therefore, resource allocation methods such as the location of cooperative relay nodes, selection criteria, and power control all affect the arrangement of antennas and the performance of the system. [0003] After searching the existing literature, it is found that the selection and power allocation of cooperative relay nodes are mostly based on a certain performance parameter, such as the interruption probab...

Problems solved by technology

The disadvantages of this method are: firstly, the utility function of this method is only set according to the attainable rate, and does not take into account the actual channel conditions of the nodes, and the income of the utility function does not match the actual situation; Due to energy constraints and other constraints, those relay nodes with poor channel conditions to the destination node should be abandoned as much as possible. Although the power price of those nodes is very low, they should be abandoned from the perspective of energy efficiency. However, there is no take this into consideration
