Wireless multi-hop relay networks have become very significant technologies in mobile communications. These networks ensure data rate transfer and coverage extension with a low cost. In this paper, two types of relay are studied; Fixed Relay Node (FRN) and Moving Relay Node (MRN). Where system analyses for uplink and downlink transmission are derived in this paper. Moreover the optimal relay location of FRN was proposed to provide a maximum achievable rate at user in cell edge region. Finally, a new algorithm was suggested to balance and control on the transmitted power of MRN over cell size to provide the required SNR and throughput at the users inside vehicle with reducing the consumption transmitted relay power.
