New Optical Channel Assignment for Hierarchical Cellular Networks

该项目研究了在所需信道总数一定的情况下，实现最高通信连通性的信道分配。根据重新包装方法，提出了几种信道分配方案；不重新包装、总是重新包装和按需重新包装。在这个项目中，这些方案的评估主要是为了实现最高的通信连通性。定量评价结果表明，在制备的微细胞通道数量和制备的微细胞和大细胞通道总数保持不变的条件下，按需重包装的性能明显优于其他方法。

This project researched the channel assignments which lead to the highest possible communication connectivity on he condition that the total number of required channels is constant. Several channel assignment schemes have been roposed depending on repacking approaches; non- repacking, always repacking, and repacking on demand. In this project, these schemes are evaluated primarily with the prospect of attaining the highest communication connectivity. The evaluations quantitatively indicate that repacking on demand may significantly outperform the others under the condition that not only the number of prepared micro-cell channels remains constant, but also the total number prepared of both micro-cell and macro-cell channels remains constant as well.
