Impact of Relay Stations Implementation on the Handover in WiMAX

摘要

Mobile WiMAX networks are generally based on the 802.16e standard. This version of standard supports a number of handover types and allows full mobility of users. However, the relay stations are not considered in this standard version. Relay stations are introduced in the originating 802.16j standard version. This paper deals with the impact of relay stations implementation from the handover point of view. The influences of fixed relay stations amount on the number of handover procedure initializations and on the diversity set size are investigated.
