1. In a computer network containing wireless communications connections, a method for optimizing transmission of information across a wireless link, comprising the steps of:

  • identifying an information base form as a template for transmission of information from a first computer to a second computer;

    comparing information to be sent across said wireless link from said first computer to said second computer with said information base form, said comparing step calculating a difference between said information base form and said information to be sent;

    performing a plurality of rebasing tests to detect whether a rebase of said information base form is indicated, wherein one of said plurality comprises performing a sharp increase detection test, said step of performing said sharp increase detection test further comprising the steps of;

    computing a mean difference since a last rebase;

    comparing said computed mean difference to a detection threshold;

    recomputing said detection threshold when said computed mean difference is not greater than said detection threshold;

    determining whether said detection threshold has been exceeded a predetermined number of times when said computed mean difference is greater than said detection threshold; and

    concluding that said rebase is indicated when said determining whether said detection threshold has been exceeded step has a positive result;

    sending said calculated difference from said first computer to said second computer;

    updating said information base form with said information to be sent when said rebase is indicated; and

    sending a rebasing indicator from said first computer to said second computer when said rebase is indicated, along with said calculated difference.
