The primary goal of Mobile Ad Hoc Networks (MANETs) is to improve energy efficiency while maintaining secure and reliable communication. The authors of this paper introduce FLEATM, an ingenious trust-based routing system that integrates energy awareness and fuzzy logic to tackle this issue. FLEATM utilizes fuzzy logic to evaluate the dependability of nodes by taking into account past interactions and present energy levels. When it comes to complex and ever-changing network environments, trust and energy measures can be quite unreliable and confusing. FLEATM employs the clever use of fuzzy logic to tackle this particular issue. The proposed approach cleverly takes into account both node energy efficiency and trustworthiness when selecting routes by integrating trust management into the routing protocol. Thanks to the nodes with high energy levels, the network life is extended as they are not affected by this twofold factor. The FLEATM trust assessment approach is really impressive since it combines suggestions from neighboring nodes with direct observations to intelligently provide comprehensive trust ratings. Simulations show proof of that FLEATM outperforms trust-based and energy-aware routing systems in conditions of packet delivery ratio, network longevity, and overall statement reliability. FLEATM’s clever flexibility allows it to quickly adjust to any changes in network conditions, making it an extraordinary choice for safe and well-organized routing in MANETs.
