A Path Selection Method in IEEE 802.16j Mobile Multi-hop Relay Networks

IEEE 802.16j mobile multi-hop relay (MMR) network provides an attractive solution for the coverage extension and throughput enhancement of IEEE 802.16e network. IEEE 802.16j MMR network needs a method for finding the RS route that minimizes the latency and maximizes the network throughput. In this paper, we propose a path selection method for IEEE 802.16j MMR network. The metrics designed for the path selection, such as link available bandwidth, Signal-to-Noise Ratio (SNR) and hop count will be discussed. We demonstrate the performance improvement with numerical results.
