Performance analysis of uplink capacity in IEEE 802.16j transparent mode

Abstract:

This paper studies system uplink capacity in transparent mode with mobile nodes and fixed relays stations in conformance with IEEE 802.16j. The study shows different simulation scenarios for evaluating uplink capacity in a Mobile Multihop Relay (MMR), with varying numbers and different positioning of relay stations in a transparent mode (T-RS), moreover, two environments are considered, an urban and a rural environment. The results show that IEEE 802.16j must be implemented in an urban environment instead of rural environment. The main conclusions determined in this work are the increase of throughput in relationship with the position of the T-RS and the effective number of T-RS that permit the maximum system increase is using 6 T-RS presenting an improvement of 14% of the system capacity. © 2012 IEEE.
