We consider a fully-connected wireless gossip network which consists of asource and $n$ receiver nodes. The source updates itself with a Poisson processand also sends updates to the nodes as Poisson arrivals. Upon receiving theupdates, the nodes update their knowledge about the source. The nodes gossipthe data among themselves in the form of Poisson arrivals to disperse theirknowledge about the source. The total gossiping rate is bounded by aconstraint. The goal of the network is to be as timely as possible with thesource. In this work, we propose ASUMAN, a distributed opportunistic gossipingscheme, where after each time the source updates itself, each node waits for atime proportional to its current age and broadcasts a signal to the other nodesof the network. This allows the nodes in the network which have higher age toremain silent and only the low-age nodes to gossip, thus utilizing asignificant portion of the constrained total gossip rate. We calculate theaverage age for a typical node in such a network with symmetric settings andshow that the theoretical upper bound on the age scales as $O(1)$. ASUMAN, withan average age of $O(1)$, offers significant gains compared to a system wherethe nodes just gossip blindly with a fixed update rate in which case the agescales as $O(\log n)$.
