The security of the wireless sensor network-Internet of Things (WsN-IoT) network is more challenging due to its randomness and self-organized nature. Intrusion detection is one of the key methodologies utilized to ensure the security of the network. Conventional intrusion detection mechanisms have issues such as higher misclassification rates, increased model complexity, insignificant feature extraction, increased training time, increased run time complexity, computation overhead, failure to identify new attacks, increased energy consumption, and a variety of other factors that limit the performance of the intrusion system model. In this research a security framework for WsN-IoT, through a deep learning technique is introduced using Modified Fuzzy-Adaptive denseNet (MF_AdadenseNet) and is benchmarked with datasets like NsL-Kdd, UNsWNB15, CIdds-001, Edge IIoT, Bot IoT. In this, the optimal feature selection using Capturing dingo Optimization (CdO) is devised to acquire relevant features by removing redundant features. The proposed MF_AdadenseNet intrusion detection model offers significant benefits by utilizing optimal feature selection with the CdO algorithm. This results in enhanced detection Capacity with minimal computation complexity, as well as a reduction in False Alarm rate (FAr) due to the consideration of classification error in the fitness estimation. As a result, the combined CdO-based feature selection and MF_AdadenseNet intrusion detection mechanism outperform other state-of-the-art techniques, achieving maximal detection Capacity, precision, recall, and F-Measure of 99.46%, 99.54%, 99.91%, and 99.68%, respectively, along with minimal FAr and Mean Absolute Error (MAE) of 0.9% and 0.11. © 2024 The Authors.

The discovery and characterization of the nuclear AUX-indole-3-acetic acid(IAA)-TIr1/AFB auxin co-receptor complex in the model plant Arabidopsis at the outset of the 21st century was a hallmark event in biological *** decades of subsequent discovery demonstrated the central role of the nuclear auxin perception mechanism in virtually every stage of Viridiplantae *** auxin receptors were also shown to be essential for later stages of differential hypocotyl,coleoptile,and root tropisms,but the most rapid responses were found to persist in Arabidopsis mutants lacking important components of the receptor mechanism(Napier,2021;Peer and Murphy,2022).In particular,rapid cellular elongation observed in tropic growth or after experimental application of auxin is mediated by H+extrusion across the plasma membrane(PM).The resulting apoplastic acidification activates extensin proteins that loosen cell walls to allow for turgor-driven cellular *** initial events occur in a time frame that precludes nuclear signaling and now can be clearly attributed to a cell surface auxin co-receptor complex and downstream signaling intermediaries.
