Abstract :
The cooperative cellular relaying network is expected to achieve the higher capacity and enlarge the coverage. In this paper, a novel cost-aware handover decision algorithm (CHDA) for cooperative cellular relaying networks is proposed. Two cost functions, namely the triggering and priority decision cost functions are exploited, which involves the signal transmission quality, the handover signaling cost, the handover latency and the interference estimation. Simulation results show that the signaling overhead and the handover delay decrease significantly by utilizing the CHDA scheme. It is also proved that the CHDA strategy is an efficient method to achieve the tradeoff among the QoS requirements and the system overheads, which can remarkably enhance the system performance.
