Abstract (in Japanese) (See Japanese page) 
(in English) In TDMA-based wireless mesh networks, time slots should be assigned to links considering interference relationships.
In graph theory-based time slot assignment algorithms, the protocol interference model is widely used to determine radio interference information, although this model is inaccurate when compared with actual radio interference.
On the other hand, the signal-to-interference-plus-noise-ratio model (SINR model) gives more accurate interference relationships.
However, it is difficult to apply SINR model to time slot assignment algorithms since the radio interference information can not be determined before time slot assignment.
In this report, we investigate the effect of parameters of the protocol interference model on the accuracy in determining interference relationships. Specifically, after assigning time slot to links based on the protocol interference model with vrious interference ratios, we compare the interference relationship among links based on the protocol interference model and that based on SINR model.
Through simulation experiments, we show that accuracy of the protocol interference model is improved by up to 15\% by adjusting the interference ratios of the protocol interference model.
