New Optical Channel Assignment for Hierarchical Cellular Networks

本课题研究了在所需信道总数不变的情况下，使通信连通性达到最高的信道分配问题。几种信道分配方案已经被提出，取决于重新打包方法：非重新打包、总是重新打包和按需重新打包。在这个项目中，这些计划主要是评估达到最高的通信连接的前景。定量的评估表明，按需重新包装可能会显着优于其他条件下，不仅准备的微孔通道的数量保持不变，但也准备的微孔和宏细胞通道的总数保持不变，以及。

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.
