Examples described herein provide a computer-implemented method that includes assigning each of a plurality of processing systems to one of a plurality of groups. Each group of the plurality of groups cycles, based on an offset time period, between an advertiser state, a listener state, and a sleep state. The method further includes connecting a first processing system of a first group of the plurality of groups to a second processing system of a second group of the plurality of groups when the first group is in one of the listener state or the advertiser state and the second group is in the other of the listener state or the advertiser state.
