Dynamic C-RAN resource sharing scheme based on a hierarchical game approach

Over the past decade, wireless applications have experienced tremendous growth, and this growth is likely to multiply in the near future. To cope with expected drastic data traffic growth, a new cloud computing-based radio access network (C-RAN) has been proposed for next-generation cellular networks. It is considered as a cost-efficient way of meeting high resource demand of future wireless access networks. In this paper, we propose a novel resource sharing scheme for future C-RAN systems. Based on the Indian buffet game, we formulate the C-RAN resource allocation problem as a two-level game model and find an effective solution according to the coopetition approach. Our proposed scheme constantly monitors the current C-RAN system conditions and adaptively responds in a distributed manner. The experimental results validate the effectiveness and efficiency of our proposed scheme under dynamic C-RAN situations.
