Context-aware Gossip in Ad hoc Vehicular Networks

The purpose of this paper is to quantify and highlight the effects of how contextually guided gossip in ad hoc dynamic vehicular networks during emergency situations perform. Two traffic scenarios are simulated, each one of the scenarios was simulated with the effect of contextual filtering and without any filtering (broadcast gossip). Our environment assumes the minimum specifications available, which is the presence of an on-board unit only in each car. We also analyze the effect of applying such filtering and if it is worth applying in such a critical environment that has human lives at stake. The simulation results show that our proposed concept could be applied safely without much affecting the time that the gossip takes to reach other vehicles. The amount of redundant and unneeded messages transmitted is reduced drastically with higher road traffic.
