The Dynamic Counter-Based Broadcast for Mobile Ad hoc Networks.

      Аннотация: This research proposes and analyses the Dynamic Counter-Based broadcasting scheme under a range of network operating conditions and applications; and demonstrates a clear benefit of the scheme when compared to its predecessors under a wide range of considered conditions. The first part of the book, sets a baseline study of the counter-based scheme analyzing it under various network operating conditions. The second part, attempts to establish the claim that alleviating existing stochastic counter-based scheme by dynamically setting threshold values according to local neighborhood density improves overall network efficiency. The third part, evaluates dynamic counting and tests its performance in some approximately realistic scenarios. The examples chosen are from the rapidly developing field of Vehicular Ad hoc Networks (VANETs). The last part, shows that routing overhead can be significantly reduced by applying dynamic counting in the route discovery process of a well-known routing protocol. The study shows a clear benefit of the proposed scheme in terms of average collision rate, saved rebroadcasts and end-to-end delay, while maintaining reachability.
