Dynamic Channel Assignment for Multihop Cellular Networks with Any Reuse Factor

A clustered multihop cellular network (cMCN) architecture is recently proposed and studied using fixed channel assignment (FCA) with a reuse factor, N_r=7. In this Letter, we propose and develop a multihop dynamic channel assignment (mDCA) scheme applicable with any reuse factor. The mDCA assigns channels with the knowledge of the information about interference in surrounding cells. Simulations show that the capacity improvements at call blocking probability of 1% for mDCA over the conventional FCA are 96% and 210% for N_r=4 and N_r=7, respectively.
