Abstract:
In one embodiment, a time at which a first device in a frequency-hopping communication network is expected to transmit a data message is determined. A first schedule is then generated based on the determined time, and the first schedule is overlaid on a frequency-hopping schedule for a second device in the network. The first schedule defines a first timeslot during which the second device listens for the data message, while the frequency-hopping schedule defines second timeslots during which the second device listens for data messages from other devices in the network. Notably, a duration of the first timeslot is greater than respective durations of the second timeslots.
