| Summary: | 碩士 === 淡江大學 === 資訊工程學系資訊網路與通訊碩士班 === 97 === In the IEEE 802.16j multi-hop relay (MR) network, the design of an effective path selection scheme is an important issue for throughput gain and overhead reduction. This paper proposes a new metric, called SEL, to evaluate the relay path and thereby determine the appropriate one among the possible paths. SEL mainly considers both link spectral efficiency and link load. Based on SEL, a comprising function is also developed to formulate the path cost to select the appropriate relay path. As confirmed by the performance evaluation, the proposed path selection scheme with SEL consideration significantly outperforms the existing path selection scheme in network throughput and map overhead.
