Abstract:
1. A method for selecting route discovery, the method comprising: determining an amount of data to be transmitted over a channel; selecting, according to the amount of data to be transmitted, symmetric path route discovery or asymmetric path route discovery for the channel prior to performing discovery of a transmission route for the channel, wherein asymmetric path route discovery is selected when the amount of data to be transmitted is greater than a threshold, and wherein symmetric path route discovery is selected when the amount of data to be transmitted is equal to, or smaller than, the threshold; and transmitting a selection result of the selecting to other nodes, wherein the transmitting initiates the performing the discovery of the transmission route for the channel; wherein the symmetric path route discovery requires that a same path be selected for an uplink and a downlink of the transmission route; and wherein the asymmetric path route discovery permits different paths to be selected for the uplink and the downlink of the transmission route.
