Abstract

The conventional approach of hybrid channel assignment strategy in cellular networks is rather inefficient due to the fact that it does not take advantage of the FCA scheme to the extreme. In this paper, we divide a cell into two parts: inner cell region and outer cell region, and apply the dynamic channel assignment and the fixed channel assignment schemes to the inner region and out region, respectively, in an attempt to fully utilize the strengths of the channel assignment schemes. In the performance evaluation, we demonstrate that the channel reuse efficiency has been improved compared to the FCA and DCA schemes. We also calculate the probability of an intracell handoff due to the use of the space partitioning. The proposed scheme can be adapted to a multi-tier structure with high/low speed mobile users, and hot spots.
