Flooding, the process in which each node retransmits every uniquely received packet exactly once is the simplest and most commonly used mechanism for broadcasting in MANETs. Despite its simplicity, it can result in high redundancy, contention and collision, collectively known as broadcast storm problem. Counter-based broadcasting scheme has been proposed to overcome the broadcast storm problem in MANET. It relies on a threshold value to decide whether or not to forward a broadcast packet. The selection of an optimal counter threshold-value of this scheme is critical to improving saved rebroadcast without degrading reachability. Previous research work has focused on determining the best counter threshold-value based on low traffic injection conditions. In this paper, we investigate the best counter threshold value for optimal performance over a wide range of standard metrics in various network traffic injection rates. Simulation results reveal new insights in the performance of the counter-based broadcasting scheme and demonstrate its sensitivity to the selected threshold-values. These results are useful for optimally setting the counter threshold-value when designing efficient counter-based broadcasting schemes.</ABSTRACT></RECORD></RECORDS></XML>
