Maximum Permissible Density of Simultaneous Transmissions in Underwater Sensor Networks

In this paper, the ratio of signal to interference for underwater acoustic channels is calculated. Based on this ratio, upper bounds on the maximum permissible density of simultaneous transmissions of underwater sensor networks that allows a certain probability of successful reception, in two different models, are determined. In the first model, the distance between source and destination is assumed to be a fixed value while in the second one, it is assumed that a power control mechanism is available in the network architecture and the distance between source and destination can be variable due to use of power control.
