Abstract

Broadcasting is considered one of the main challenges in Mobile Ad-hoc Networks (MANETs). Therefore, several algorithms have been proposed, such as Self-Pruning (SP), Counter-Based (CB) and Dominant-Pruning (DP). However, they suffer from low packet delivery in some environments, such as the mobility scenario. This paper presents Reliable Neighbor-Based Broadcasting (RNBB), an efficient broadcast algorithm which can meet the broadcast requirements in MANETs. The design principle is to construct a hybrid scheme between SP and CB broadcast schemes aiming to combine the advantages of the both. To make the solution robust, new ideas such as adaptive broadcast delay and an eavesdropping mechanism are integrated to enable RNBB to mitigate the broadcast storm problem while ensuring highly reliable packet delivery. To evaluate RNBB, a comprehensive comparison with different developed algorithms has been made using ns-2. The experimental results demonstrate that RNBB provides robust performance across a wide range of environments.
