Abstract:
1. A method for channel mapping based on frequency hopping, the method comprising: computing a working channel label of a node according to a number of working channels of the node in a frequency hopping mode, an identifier of the node, and a time parameter corresponding to a current superframe; determining a working channel according to the working channel label; and transmitting data on the working channel within the current superframe, wherein the number of working channels of the node in the frequency hopping mode is a number of other working channels of the node in the frequency hopping mode than a spare channel and a prescribed channel in a network, and wherein determining the working channel according to the working channel label comprises when the working channel label is greater than or equal to either a label of a prescribed channel or a label of a spare channel, increasing the working channel label by a preset value repeatedly until an accumulated working channel label does not equal the label of the prescribed channel or the label of the spare channel, wherein determining a channel corresponding to the accumulated working channel label as the working channel, and wherein the preset value is a difference between labels of neighboring working channels in the network.
