1. A method, comprising:

  • determining, via data processing circuitry, error rate metrics of data transmissions over a constrained application protocol (CoAP) using a first CoAP segment size;

    determining, via the data processing circuitry, a second CoAP segment size for the data transmissions based at least in part upon the error rate metrics;

    wherein determining the error rate metrics comprises determining a current error rate of the data transmissions and determining a historical average of error rates of the data transmissions and wherein determining the second CoAP segment size comprises;

    weighting the current error rate to obtain a weighted current error rate;

    weighting the historical average of error rates to obtain a weighted average;

    summing the weighted current error rate and the weighted historical average to obtain a manipulated variable; and

    correlating the manipulated variable with a corresponding CoAP segment size to obtain the second CoAP segment size.
