With the rapid growth of the number of connected devices that exchange personal, sensitive, and important data through the IoT based global network, attacks that are targeting security services are increasing as well. Accordingly, there is a need for security solutions that are suitable for IoT environment. A network intrusion detection system (NIDS) is a solution that examines network traffic and alerts system administrators if there are security breaches. In this paper, an enhanced version of pigeon-inspired optimization (PIO) is proposed which enhances PIO by adding a local search algorithm named (LS-PIO). Moreover, an ensemble learning approach, which is based on multiple one-class classifiers, has been used in order to improve the performance of proposed NIDS. Four benchmark datasets were used to evaluate the LS-PIO and ensemble based NIDS which are BoT-IoT, UNSW-NB15, NLS-KDD and KDDCUPP99. The evaluation took into consideration F-score, accuracy, AUC, FPR and TPR. Results show that the suggested approach outperforms other NIDS techniques that are selected from state-of-the-art relevant research found in the literature.
