In this paper, we have investigated power control techniques for two different routing schemes in a multihop Code Division Multiple Access (CDMA) packet radio network. These techniques control the signal power based not only on the transmission distance, but also on the transmission direction. These techniques reduce the amount of interference from the other terminals, and improve the probability of packet success and the expected forward progress per hop. Our results show that the power control techniques increase the expected packet progress towards the final destination per hop by 16% as compared with that of the no power control case. This performance improvement is achieved without increasing system complexity or sacrificing system performance. power control CDMA, packet radio network.
