In this paper, we propose a clustered multihop cellular network (cMCN) architecture and study its performance using fixed channel assignment (FCA) scheme for uplink transmission. The proposed cMCN using FCA can be applied with some reuse factors. An analytical model based on Markov chain is developed to analyze its performance and validated through computer simulation. And then, we implement Direct Peer-to-Peer Communication (DC) in cMCN by considering more reasonable conditions in reality. DC means that two calls communicate directly instead of going through base stations. The results show that cMCN with FCA can reduce the call blocking probability significantly as compared with the traditional single-hop cellular networks with FCA and can be further reduced by using DC.
