Abstract:
1. In a wireless network system having a plurality of nodes, which include a transmitting node and a target node that communicate with each other, and which share a frequency hopping pattern among the plurality of nodes, the shared frequency hopping pattern including channels associated with a series of time slots, the time slots each having an allocated link between two of the nodes, a method comprising: providing a channel list table which includes, for each transmitting node, one or more channel lists, each channel list containing conditions of the channels of the shared frequency hopping pattern that include at least one available channel for communications with a target node; selecting a channel of a next allocated time slot from the shared frequency hopping pattern at the transmitting node; selecting the channel list for the target node from the channel list table, to which the transmitting node transmits; checking if the selected channel is available based on the selected channel list; setting the selected channel at the transmitting node if the selected channel is available; and calculating a substitute channel from the channel list in place of the selected channel at the transmitting node if the selected channel is not available.
