A cross-layer based optimized feature selection scheme for intrusion detection in wireless sensor network

Abstract

The Wireless Sensor Networks (WSNs) contain a significant quantity of sensor nodes that computes and communicates for data transmission. The data packet sensed and transmitted contains various cross layer feature set that includes many important information. Many essential aspects, which include storage capability, consumption of energy, and, computational power should be taken into account while dealing with the data packets. On the other hand, many past researchers have carried out their work in order to detect intrusion utilizing cross-layer packets but fail in detecting them at the same time. Cross-layer and feature selection techniques play a key role in building an efficient Intrusion Detection System (IDS). An advantage of using the cross-layer technique is to achieve a higher correlation among different layers of the protocol so that one layer can use the parametric information of the other layer by breaking the traditional layer barriers. In this work, we propose a cross-layer based multi-feature selection model for intrusion detection in WSNs. Firstly, an optimized multi-feature selection algorithm is proposed for selecting efficient and useful features from the cross-layered architecture of the network. Secondly, a multi class intrusion detection model is proposed for the classification of different cross-layer based intrusion in the network. The proposed algorithm is developed for providing total security to cross-layer based networks by selecting prominent features and detecting intrusion at the same time. The simulation results are utilizing on real-time intrusive data from the network by analyzing the proposed model.
