The increase in performance for the hybrid systems obviously
comes at the cost of increased traffic due to local
data transmission. The static hybrid system utilizes the local
dissemination strategy all the time and is therefore considered
the upper bound for traffic as shown in Figures 5g and 5h. As
the peer-to-peer dissemination protocol exploits the event semantics
to limit message forwarding, the local traffic increases
with the size of the AoI. The adaptive strategy, in turn, reduces
the local traffic by switching the dissemination protocol off
in cases when the AoI of a node is empty. Furthermore, by
switching to the probabilistic protocol, the traffic for larger
AoIs is reduced as well compared to the static hybrid system.
