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 study 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 study. 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. Numerical results indicate an enhancement in received signal strength for users at the cell edge from (-90 to -65) dBm and 40% increment from all cell size after deploying FRN at proposed locations. As well as, the results revealed that there is saving nearly 75% from transmitted power in MRN after using proposed algorithm. ATDI simulator was used to verify the numerical results, which deals with real digital cartographic and standard formats for terrain.

ABSTRACT:Previous work has been done in [1], [2], [3], [4], which focuses on system level description of the user concept of cooperation. It concentrates on physical layer issues, with the anticipation that any higher level overhead will be negligible compared to the gains. The type of cooperation focused on , is the cooperation of active users, i.e., users who have information of their own to send and thus do not want to simply be another user's relay. Cooperative relaying is an effective technique to combat multipath fading, improve system capacity and enhance the coverage. Initially, capacity analysis of Gaussian relay channel was comprehensively studied in [6]. For network scenario, capacity has been analyzed in [7]. Coding strategies that exploit node cooperation has been developed in [8] for relay networks. Outage probability of multi-hop amplify and forward relay system has been analyzed in [9]. In [10], closed form expressions of average bit error rate, amount of fading and outage probability have been derived for Rayleighfading channel where relay works in non-regenerative mode and destination performs equal gain combining. An overview of various cooperation schemes and issues related to their implementation has been discussed in [11]. Various power allocation strategies for non-generative relay network have been studied in [12]. In [13], closed form expressions of outage probability and bit error rate (BER) for binary phase shift keying (BPSK) are derived for the case where communication between source and destination is supported by multi antenna relay and both relay and destination perform maximum ratio combining (MRC) of signals in Rayleigh fading channel. Outage probability and average error rate of two-hop multi antenna relay based system for the case when relay performs selection combining (SC) of signals and destination performs MRC of signals are analyzed in [14] and [15], respectively. Closed form expressions of BER have been established in [16] for two-hop multi antenna cooperative relay network in Rayleigh fading channel. Here, destination performs selection combining of signals received from source, relay and relay performs selection or MRC combining of signal. In [17], analytical expressions of average received SNR, outage BER and channel capacity has been established for the case when source and relay are communicating with multi-antenna destination in Rayleigh fading channel. Closed form expression of outage probability has been derived in [18]; here, communication between source and destination is supported by two multi-antenna relay nodes.
