Once the number of nodes reaches the second threshold ∆p, the protocol is switched to the probabilistic scheme. Nodes that are moving at the verge of another node’s AoI could lead to oscillations if they frequently join and leave the AoI. Finding matching subscribers for an event already includes calculating the distances between nodes. Therefore, the strategy can be further extended by taking the node distances into account without introducing additional computational cost. By neglect- ing nodes that are located in close proximity to the AoI bounds, oscillations are avoided.
