Inspired Counter Based Broadcasting for Dynamic Source Routing in Mobile Networks

The broadcast storm problem is one of the most challenging issues in Mobile ad Hoc Networks (MANETs). However, it is still a challenging problem despite the great deal of related works and existing solutions. Dynamic Source Routing Protocol (DSR) is one of the well-known on-demand routing protocols that has been widely studied and analyzed over the past few years. However, there is a lack of methods and solutions for the broadcast storm problem in DSR under the umbrella of dynamic operating conditions. Thus, to improve the routing discovery process in DSR we incorporate a new counter based broadcast algorithm in DSR, namely, Inspired Counter Based Broadcasting (DSR-ICB). The new variants are based on the counter based approach which reduces the number of redundant packets. Simulation experiments have been conducted in different scenarios. The results illustrate that the proposed algorithm has significantly improved the DSR in terms of a number of important metrics such as saved rebroadcasts, reachability, end-to-end latency, packet delivery ratio.
