Summary :

We previously developed a novel transmission power control method for code-division multiple access (CDMA) wireless systems that is suitable for the transmission control protocol (TCP) and constant bit rate (CBR) connections. It allows each mobile terminal to send packets to arbitrary slots without negotiation or the use of the ALOHA protocol. It results in high bandwidth utilization for TCP connections without the need to modify the TCP protocol or use a snoop agent. In this paper, we improve our previously developed power control method so as to adapt itself to distance variations and instantaneous fluctuations in the received power due to fading. We show that the developed method enables efficient bandwidth utilization compared with the conventional power control technique under various conditions.
