New Approaches for Relay Selection in IEEE 802.16 Mobile Multi-hop Relay Networks

The IEEE 802.16 mobile multi-hop relay (MMR) task group ’j’ (TGj) has recently introduced the multi-hop relaying concept in the IEEE 802.16 WirelessMAN, wherein a newly introduced relay station (RS) is expected to increase the network performance. In this context, we consider the problem of path selection where several RSs might exist between the base station (so called, MR-BS) and the mobile station (MS). We propose a backward compatible signaling mechanism and a path selection algorithm based on the expected link throughput (ELT). To the best of our knowledge, this is the first contribution that presents path selection algorithm in the IEEE 802.16 networks. Performance of the proposed scheme is compared with shortest hop and no-relay schemes and we show our schemes significantly improves the performance in terms of throughput and latency.
