Abstract (in Japanese) (See Japanese page) 
(in English) On time slot assignment in IEEE 802.16j multi-hop relay networks, the interference relationships among links are often estimated by the interference estimation methods based on the network topology information. However, these methods cannot take into account wireless link quality. The effective time slot assignment would be possible by the interference estimation methods utilizing detailed wireless link quality, resulting in the higher network performance. In this report, we evaluate the performance of time slot assignment algorithms based on various interference estimation methods. Through performance evaluations with simulation experiments, we clarify that the sensitivity of the control parameters in interference estimation method on the network performance. Moreover, we demonstrate that by carefully tuning the control parameter, the interference estimation method based on the network topology information can achieve almost the equivalent performance as the method requiring wireless link quality.
