Abstract: Wireless sensor networks（WSNs） face significant security challenges due to their open communication frequencies, protocols, and lightweight security design.This paper introduces a novel secure clustering routing algorithm, termed HFSC,which integrates the hiking optimization algorithm（HOA） with a fuzzy inference system（FIS） to improve both network longevity and security.HFSC addresses cluster head selection as a multi-objective optimization problem and employs a non-dominated sorting-based multi-objective HOA（NSHOA） to assess potential cluster heads using a range of node performance metrics.Subsequently, FIS is utilized to finalize cluster head selection by incorporating node trust values.MATLAB simulations demonstrate that HFSC achieves a reduction in average energy consumption by 55.9%,39.2%,and 8.2% compared to the HiTSeC,ICITS and NSMMA algorithms, respectively.Additionally, it extends network lifetime by 42%,35% and 13%,while ensuring secure clustering throughout the network.
