Adaptive counter-based broadcasting scheme in mobile ad hoc networks

Mobile Ad hoc Networks (MANETs) are formed by wireless devices that communicate without necessarily using the preexisting network infrastructure such as base station/access point. Broadcasting is a common operation in wireless Mobile Ad Hoc Networks (MANETs) that can be simply applied by using flooding. However, this technique suffers from a number of drawbacks in terms of high redundancy, collision, and contention. This phenomenon is known as the broadcast storm problem. Many schemes have been proposed to address this problem. In this paper we examine the performance of counter-based scheme with adaptive threshold which aims to increase the reachability percentage of the transmission packets which receive the broadcast message, to all nodes with high reachability. The proposed scheme increases the throughput of the network, as the simulation experiments conducted by using ns-2 simulations, show. We evaluate the performance of our approach by comparing it with the simple flooding. Simulation results show that our approach performs better than simple flooding in the average end-to-end delay (Latency), The Packet Delivery Ratio, and Routing Overhead.
