Abstract

Wireless multi-hop relay systems have become very important technologies in mobile communications. These systems ensure high-speed data transfer and extended coverage area at a low cost. In this paper, we proposed two scenarios. In the first scenario we studied the performance of a two-way multi-hop relay network and proposed a half-duplex mode amplify-and-forward relay with two cases. In the first case, we studied a fixed relay node (FRN) with (qth) users for two-way performance keeping user equipment (UE) is fixed and is moving at different velocities toward FRN. In second case, we proposed a new connection between the (kth) moving relay nodes (MRN) and users had the same the velocities and times, in which users are independently moving between them. In the second scenario the balanced power algorithm for MRN is proposed, this algorithm is control of the transmitted power over cell radius to achieve the required SNR and throughput at the users with reducing the consumption transmitted relay power. Is has been shown from the simulation results that there is saving nearly 75% from transmitted power after using proposed algorithm.
