Abstract:
1. A method for controlling a network, comprising: communicating among a plurality of nodes in a network of wireless communication devices using a frequency hopping method by varying a Radio Frequency (“RF”) carrier wave frequency for said communicating among a set of hop frequency channels in accordance with a frequency hopping sequence; prior to a network transition time from a first RF carrier wave frequency of said frequency hopping sequence to a second RF carrier wave frequency in said frequency hopping sequence, selecting a first group of control channels from a plurality of control channel groups, where transmitting, by a coordinator node, a first hop announcement on the first group of control channels, said first hop announcement specifying the second RF carrier wave frequency; beginning a dwell time duration at a time specified by the coordinator node during which the second RF carrier wave frequency will be used by the network for said communicating; and receiving at said coordinator node during said dwell time duration a message from a subordinate node of said plurality of nodes; wherein the coordinator node continually and iteratively cycles though said plurality of control channel groups such that a different one of the control channel groups is selected with each network frequency hop.
