Abstract

This study evaluates the effect of the choice of frame structure type in WiMax networks employing non-transparent relay stations (ntRS). The IEEE 802.16j-2009 amendment allows two frame structure types, single frame and multi frame. Thus far, a comparison of the two choices, in terms of network performance, has not been made. To facilitate this evaluation, we expand on Light WiMax (LWX) ns2 add-on to support ntRS, the two frame structure types, in addition to the relevant operational requirements (e.g. QoS support). We observe that while the multi-frame structure allows for higher throughput and voice capacities, the single frame shows some general advantage in terms of delay.
