The relay task group has extended the IEEE 802.16e-2005 to a new standard known as IEEE 802.16j Mobile Multi-hop Relay (MMR). The deployment of relay station (RS) in WiMAX network will overcome the increase in cost and improve the economic viability of the system. Furthermore, the MMR standard also addresses the problem of limited spectrum, low SINR at the cell edge and coverage hole of the previous standard. However, the introduction of relay may cause longer delays and degrade the performance of resource efficiency. In this paper, we investigate the performance analysis of polling delay for transparent and non-transparent relay modes in MMR WiMAX. We derived and analyzed the average polling delay of both modes using M/M/1 and tandem queue respectively. Numerical result has shown that the average polling delay decreases when the number of poll increases for both relay modes. Moreover, the delay for non-transparent relay mode is higher due to the signals overhead.
