Continuous growth of cellular subscribers as well as demands for high-speed and high-quality multimedia services have made it necessary to increase system capacity and data rate. On the other hand, the energy consumed goes up accordingly as the data rates increases. Therefore, designing an efficient resources allocation scheme and architecture to improve the output performance and reduce energy consumption will be the focus for future research. In this paper, we propose an opportunistic relay selection technique to save energy consumption for future Green multihop cellular networks. Then, we developed a comprehensive simulation model with consideration of path loss, shadowing, inter-cell and intra-cell interference and other service requests for both single hop and multi-hop TDD-CDMA based cellular system to conduct a deep investigation of energy consumption including the hardware energy for different RS selection under various time slot allocation schemes.
