Abstract: Two different relay modes are defined in IEEE 802.16j WIMAX standard: transparent mode and non-transparent mode. The non transparent mode is used to extend the coverage area of base stations, where low cost relay station of equal capacity as that of base station is placed at suitable position. Time taken to accept mobile stations and Bandwidth allocation are main problems in non transparent mode. In this paper we have studied Network topology acquisition, ie. the process of setting channel ID for mobile stations, and time taken to accept a new mobile station. The mobile stations which are in the coverage area of base station are given first preference, and those outside coverage area are assigned channel ID through relay stations. Two ID's are set for each mobile station: Basic channel ID [1, 2, 3….] and Primary Channel ID [256, 257, 258…]. Mobile stations are first accepted by base stations, to allocate band width. We have studied the time taken to accept mobil!
e stations. The results show that, base station takes 0.0096613 sec to accept one mobile station (inside coverage area) and it takes 0.065001 sec to accept one mobile station (outside coverage area)- through a relay station . Here 0.085308 sec is spend to accept one relay station. The results also show that the base station takes 6.727976 times more time to accept one mobile station outside coverage area.
