Abstract

The invention relates to an auction-based relay selection strategy and power allocation method in selection cooperation, and belongs to the technical field of cooperative communication. In the relay selection strategy, the auction theory is implemented between the source nodes that need to cooperate and the candidate relay nodes to select the best relay. Through the auction method, in the form of monetary compensation, the resource-rich nodes are encouraged to assist the resource-poor nodes more nodes to realize incentive cooperative transmission and share network resources. In the power allocation method, each candidate relay allocates its own transmission power and cooperative transmission power according to energy and channel quality, and competes for the most suitable cooperative transmission power through a sealed auction method, so that a single node can guarantee its own data transmission reliability. At the same time, it can assist other nodes to the maximum extent, thereby improving network transmission performance. The invention can promote the cooperation among the source nodes, and realize the rational allocation of resources while improving the reliability of data transmission.

Description

technical field [0001] The invention belongs to the technical field of cooperative communication, and in particular relates to an auction-based relay selection strategy and a power allocation method in a selected cooperative network with limited energy and resources. Background technique [0002] Selecting the cooperation technology can achieve the same transmission performance as the distributed space-time code with only a single relay cooperation, and has the characteristics of simplicity and high efficiency, so it is very suitable for application in wireless networks. In the selection cooperation, the choice of the best relay is directly related to the performance of the system and node transmission. At present, most studies assume that the relay nodes in the network have sufficient energy. Whenever necessary, the relay nodes will fully assist other source nodes in data forwarding, so as to achieve better transmission reliability in general. However, in actual networks, ...
