1. A method, comprising: generating a rendezvous request message, the rendezvous request message specifying a channel C and a rendezvous time T for which a distributed message is to be transmitted in a frequency-hopping computer network, and a priority indicating the importance of the distributed message to be transmitted on channel C at time T, wherein the computer network operates with one or more broadcast timeslots in a frequency-hopping sequence; comparing a) transmission overhead and latency associated with transmitting the rendezvous request message, to b) waiting for a subsequent broadcast timeslot; determining, based on the comparison, if it is worth waiting for the subsequent broadcast timeslot to transmit the distributed message; in response to the determining that it is not worth waiting for the subsequent broadcast timeslot, transmitting the rendezvous request message on one or more channels used in the computer network, the one or more channels based on reaching a plurality of intended recipients of the distributed message with the rendezvous request message prior to rendezvous time T, and transmitting the distributed message on channel C at rendezvous time T; and in response to the determining that it is worth waiting for the subsequent broadcast timeslot, transmitting the distributed message during the subsequent broadcast timeslot.
