Claim Text:
1. A method, comprising: determining a time at which a first device in a frequency-hopping communication network is expected to transmit a data message; generating a first schedule based on the determined time, the first schedule defining a first timeslot during which a second device in the network listens for the data message; overlaying the first schedule on a frequency-hopping schedule for the second device, wherein the frequency-hopping schedule defines second timeslots during which the second device listens for data messages from other devices in the network, and a duration of the first timeslot is greater than respective durations of the second timeslots; and setting the duration of the first timeslot based on a predetermined maximum amount of retransmissions necessary for the second device to receive the data message.
