Abstract
A method (of operating an end node) includes: wirelessly receiving an instance of a non-hopping beacon signal, B, periodically-transmitted from a central node; interpreting a frequency-block hopping guide (FBHG) according to FN(i) and IDCN thereby to determine a corresponding set, CSET(i), of at least two channels available to the end node for transmission, respectively, during frame FN(i); selecting, at least pseudo-randomly, at least one channel amongst the set CSET(i); and wirelessly transmitting at least one message from the end node using the at least one selected channel, respectively. Each instance B(i) includes: a corresponding frame number, FN(i); and an identification, IDCN, of the central node. The FBHG establishes: a total of L frames; a set of channels CSET for each frame, respectively; and that, for any two consecutive ones of the L frames, FN(j) and FN(j+1), the corresponding sets CSET(j) and CSET(j+1) will be different, CSET(j)≠CSET(j+1).
