Energy-based detection of multi-layer flooding attacks on wireless sensor network

Abstract

Ensuring cyber security on Wireless Sensor Network (WSN) is a challenging task since nodes are devices with very limited resources. Existing Intrusion Detection Systems (IDSs) solutions either ensure protection from attacks at one specific OSI layer, or they ensure multi-layer protection but with more relevant computational costs. In this work we propose a new solution which aims at detecting attacks at different OSI layers by minimizing the number of features required to perform intrusion detection activities on a WSN node. In this work we consider multi-layer flooding attack performed at routing and application layers; our experimental tests show that a high correlation exists between the features of these attacks available at the corresponding layers and energy consumption. This allows to use energy consumption as the only feature to detect both the attacks even if they are performed at different OSI layers. © 2014 Springer International Publishing.
