8. A method of updating a subsea telecommunication system, the method comprising:
measuring one or more environmental parameters;
characterizing noise in an acoustic communication channel based on the one or more environmental parameters;
characterizing the acoustic communication channel based on the one or more environmental parameters;
characterizing a physical layer parameter based on the noise in the acoustic communication channel and the acoustic communication channel;
selecting a first mode of operation of an underwater vehicle, wherein the first mode of operation is one of a traversing mode or an inspecting mode;
determining a plurality of data delivery parameters corresponding to the first mode of operation of the underwater vehicle, the data delivery parameters including at least one of latency of a data feed from the underwater vehicle, fidelity of the data feed, spatial resolution of the data feed, or temporal resolution of the data feed, wherein:
when the first mode of operation is the traversing mode, the latency of the data feed is prioritized over the fidelity of the data feed; and
when the first mode of operation is the inspecting mode, the fidelity of the data feed is prioritized over the latency of the data feed;
prior to communicating acoustically with the underwater vehicle through water:
conducting a communication performance simulation of the acoustic communication channel with the characterized physical layer parameter and the determined plurality of data delivery parameters; and
adjusting the physical layer parameter in response to the communication performance simulation;
receiving data acoustically through the water from the underwater vehicle while operating the underwater vehicle at the first mode of operation;
determining that a variation between the characterized physical layer and the data from the underwater vehicle exceeds a threshold;
recharacterizing the physical layer in response to the variation exceeding the threshold, and updating the communication performance simulation;
detecting the underwater vehicle changes operation from the first mode of operation to a second mode of operation, wherein the second mode of operation is different from the first mode of operation, and is one of the traversing mode or the inspecting mode;
adjusting the data delivery parameters to correspond to the second mode of operation, wherein the data delivery parameters are prioritized according to the second mode of operation; and
further updating the communication performance simulation using the adjusted data delivery parameters.
