Relay selection in cooperative communication with bipartite graph
摘要
Abstract
Reasonable relay selection on cooperative communication system plays an important role in optimizing system energy efficient.In order to obtain higher energy efficiency and reduce the complexity of the system,this paper proposed a relay selection strategy based on bipartition graph.The strategy mainly transformed the relay selection problem of cooperative communication system into a maximum matching problem of weighted bipartite graph for multiuser,multi-relay cooperative communication system.Firstly,this strategy considered the user node and the selected relay node as the vertices of the bipartite graph.According to the cooperative range of the relay,the strategy could determine the edge set of the bipartite graph.And then,it would assign the energy efficient generated by different cooperative combinations to each edge.Finally,the strategy could solve the maximum matching of the weighted bipartite graph by KM algorithm.Simulation results indicate that compared with other relay selection algorithms,this strategy can effectively improve the system energy efficiency,and has the advantages of low complexity.关键词
