The inherent wireless nature of these networks introduces significant security challenges. However, recognizing that routing plays a pivotal role in most mobile ad hoc network operations, enhancing the security of routes can contribute to overall network performance. This paper introduces a novel technique aimed at improving intrusion detection in mobile ad hoc networks by identifying and detecting black hole nodes. The proposed solution involves the introduction of the S-DSR protocol, a variant of the DSR protocol. The primary objective is to enhance intrusion detection by identifying black hole nodes during the route detection phase and subsequently excluding routes containing them. This ensures secure data transmission and reception within the network. The protocol, named S-DSR, is designed to address these security concerns. The results obtained from simulations conducted in the NS-2 environment indicate that the S-DSR protocol outperforms the traditional DSR protocol in terms of network performance. https://www.tmachineintelligence.ir/article_181432_36487670b36a7e42c844148a33858ffc.pdf
