“…However, it does not consider the distribution of mobile stations, so the path is selected based on the topology information only including RSs. In [12], the authors propose a route metric including load balance factor in other to prevent such a situation that some RSs suffer from heavy traffic load. Their proposed scheme helps the fair bandwidth consumption among RSs, but it does not mean the smallest bandwidth consumptions to be achieved by the highest available data rate.…”

The IEEE 802.16 mobile multi-hop relay (MMR) task group 'j' (TGj) has introduced the multi-hop relaying concept in the IEEE 802.16 Wireless MAN, wherein a relay station (RS) is employed to improve network coverage and capacity. Several RSs can be deployed between a base station and mobile stations, and configured to form a tree-like multi-hop topology. In such architecture, we consider the problem of a path selection through which the mobile station in and outside the coverage can communicate with the base station. In this paper, we propose a new path selection algorithm that ensures more efficient distribution of resources such as bandwidth among the relaying nodes for improving the overall performance of the network. Performance of our proposed scheme is compared with the path selection algorithms based on loss rate and the shortest path algorithm. Based on the simulation results using ns-2, we show our proposal significantly improves the performance on throughput, latency and bandwidth consumption.
