Abstract
This paper presents a performance analysis of the uplink capacity in a Mobile Multihop Relay (MR), by using Transparent Relay Station (T-RS) and Non-Transparent Relay Station (NT-RS) modes in conformance with IEEE 802.16, in different simulation scenarios by varying the position and the number of RS in an urban environment associated with COST 231 propagation model. The results shows that IEEE 802.16 has better performance by using RS in non-transparent mode. It was distinguished that the maximum network efficiency reaches a value of up to 90%, and the increment of the RSs in each mode allowed to increase the efficiency of network by at least 4% in transparent mode per each T-RS, whilst in non-transparent mode for each additional NT-RS the efficiency increases by around 5%.
