| Abstract(in English) | In IEEE 802.16j relay networks, time slot assignment has large influence on link transmission quality and resulting transmission bit amount because it is affected by interference signals from nodes using the same time slot. Furthermore, when adaptive modulation and coding is employed for data transmission on wireless links, the transmission bitrate is highly dependent on the link transmission quality. Therefore, we need to assign time slots t0 links considering the balance between traffic load and transmission quality of each link because links with insufficient or excess transmission bit amount against traffic loads cause the waste of wireless resources and the degradation of network perf)rmance. In this report, we propose a balancing algorithm of time slot assignment for IEEE 802.16j relay networks, considering traffic demand and link transmission quality. The proposed method adjusts the number of required time slots of links according to their traffic loads. Performance evaluation results exhibit that the proposed method improves data transfer throughput by up to around 500%. |
