FAST FREQUENCY HOPPING ADAPTED TO THE ENVIRONMENT

摘要

A transmitting node in an industrial wireless network transmits a first number of bits to a receiving node, where at least one bit is partitioned into segments and each segment is transmitted at a different frequency according to a frequency transmission scheme. The receiving node receives the number of bits, determines the quality of each segment of a received bit, collects quality determinations of segments, forms a quality measure for each frequency through combining quality determinations of the corresponding frequency, compares each quality measure with a quality measure criterion, determines at least one frequency that does not fulfill the quality measure criterion and informs the transmitting node about frequencies for which the corresponding quality measures do not fulfill the quality measure criterion. The transmitting node receives the information and updates the frequency transmission scheme.
