the concept of multi-hop CDMA cellular networks has received increasing attention now. It is a widely accepted assumption that using multi-hopping in cellular networks will increase the cellular throughput. There are several advantages of MCN such as the improved signal quality and higher coverage. Finding an available relaying path is a critical prerequisite for the success of the multi-hop cellular networks and has a great impact on the network throughput. Most works use signal strength, distance and power consumption as routing criteria, but the effect of interference specially intercell interference does not take into account in routing algorithms. For this reason, in this paper interference is calculated at any receiver during the uplink, and a novel routing scheme based on minimum interference and best link gain in each hop, is proposed. Simulation results indicate that the routing algorithm based on our proposed metric results in higher throughput than the other metrics under a certain constraint.
