Abstract :
Relay based multihop cellular system is a promising technique to improve the signal quality in wireless networks. Here, we propose the channel partitioning and relay positioning schemes so as to maximize the number of users admitted in a cell. A user is admitted if the required rate can be provided to it. Based on this scheme, signal to interference and noise ratio (SINR) received by base station (BS) and fixed relay nodes (FRN) are analyzed with emphasis on users at disadvantaged places (worst case SINR). The results show that, optimally deploying FRNs reduced the call blocking rates at least by 30% and improve the SINR significantly.
