Interference Management for Medium Access Control in CDMA Underwater Acoustic Sensor Networks

Overview One of the major challenges for the deployment of Underwater Acoustic Sensor Networks (UASN) is the design of a suitable Medium Access Control (MAC) protocol, and CDMA has been earmarked as the most promising candidate. While several works have considered the problems of allocation of code and transmission power separately, this paper, proposes a receiver-centric interference management approach for joint code/power assignment for MAC in CDMA UASNs. Through extensive numerical simulations, the paper illustrates its efficacy and demonstrate its superiority to conventional transmitter-centric approaches, for both fixed-power code assignments and joint code/power assignments.
