Abstract:
An efficient scheduling for relay networks is proposed in consideration of the signaling overhead. A source node informs both relay and destination node about the resource assignments in every frame. The resource allocation process generates a substantial signaling overhead, which influences the system performance. However, the amount of the signaling overhead can be reduced by predetermining resource assignments of future frames. We develop a frame structure for scheduling and propose an efficient scheduling in consideration of the signaling overhead. The performance of the proposed scheduling is evaluated compared with that of the conventional scheduling in terms of the average capacity as both the number of relays increases and the average signal-to-noise ratio increases. Simulation results show that the average capacity of the proposed scheduling is greater than that of the conventional scheduling.
