The present invention provides a medium access control (MAC) protocol for the collision-free transmission of packets into a channel, such that nodes are assigned time slots for collision-free transmission based on the knowledge they acquire regarding the constituency of their local neighborhoods and the advertisements of the time slots when nodes in local neighborhoods will attempt to transmit again. The scheduling procedure may utilize an age of the network together with the unique identifiers of nodes. The candidate transmission times for each node are determined using a list of the subsequent transmission times advertised by other nodes. The node discards the advertised transmission times from the list of potential transmission times, and computes its candidate transmission times using a function that provides a varying (pseudorandom) distribution of outputs for a varying sample of inputs. This function may be a hash function, an encryption function, or a table-lookup function. The computation of candidate transmission times uses the identifiers of those nodes for which no advertised transmission time has been obtained.
