Fuzzy Logic Based Broadcasting Scheme for Mobile Ad Hoc Network

Broadcast is generally used to disseminate specific information to whole nodes in mobile ad hoc networks. However, the broadcast storm problem, characterized by excessive packet collisions and redundancy, severely impairs network performance. To address this, researchers have developed enhanced broadcasting techniques, including fuzzy logic-based schemes. However, many existing fuzzy-based approaches lead to a large number of redundant packets by considering too general pa-rameters. To overcome the mentioned problem, in this paper, we propose a new fuzzy logic-based broadcast scheme to reduce the duplicated number of packets. In the proposed scheme, fuzzy logic is designed with connection time, the number of neighboring nodes, and signal strength to decide to forward in a receiver-based approach. Finally, our scheme outperforms previous work in the aspects of the number of redundant messages and network overhead.
