A joint power control algorithm for ad hoc networks based on code division multiple access (CDMA) was studied. Firstly, the new algorithm was deduced in theory. Then, the system model was developed. In the proposed algorithm, all transmitting nodes assigned in the same time slot adjust their transmitter power based on current information, which takes into account the adjustments of transmitter power of other transmitting nodes in next step and the prediction of inter-link interference power level at the receive node. Simulation results indicate that the proposed algorithm outperforms the conventional algorithms in terms of smaller standard deviation of receiver signal-to-interference-ratio, lower system interference and higher energy efficiency.
