| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In IEEE 802.16j-based wireless multihop relay networks, the locations of relay nodes and the network topology are important factors in achieving high performance. In particular, radio wave interference must be con- sidered when determining node locations. However, nodes are generally deployed in limited areas and it is difficult to move them to arbitrary positions. In this report, we propose a node repositioning method that works within such constraints to improve network performance. Since the computational cost is high for assessing all possible node positions, the proposed method limits the number of candidate nodes to be repositioned on the basis of distance information. We examine the effectiveness of the proposed method through simulation experiments and show that a performance improvement of up to 28% is realized by repositioning 30% of nodes and that nearly optimal results can be obtained, but at lower computational cost than an exhaustive search. | |
