Performance analysis of distributed and centralized scheduling in two-hop relaying cellular system

We consider the resource allocation of centralized and distributed scheduling in the two-hop relaying cellular system. The limited spectrum resource is one of the obstacles which conflicts with the evolution of being wider coverage and larger capacity in the wireless system. In this paper, system performance and signaling overhead are analyzed and compared. Then we propose a novel routing strategy for choosing the access link and three practical scheduling strategies. Simulation results are provided and analyzed in several scenarios, which show the benefit of adopting the relay technique.
