Abstract
In most sensor networks, sensor nodes are vulnerable to many security attacks because of open and harsh environment. In false report attacks, an attacker can capture some sensor nodes and inject false reports into the network through the compromised nodes. The false reports injected may confuse the user and more importantly deplete the limited energy of the network. Several filtering schemes are employed to detect and drop false reports at an early stage, for example, the commutative cipher-based en-route filtering scheme (CCEF). In the CCEF, each forwarding node performs verification of received event reports based on a probability without consideration of false traffic ratio. Hence, it is difficult to adapt to the change of false traffic ratio. That is, it is possible that the network performs too many or too few filtering operations, which results in energy inefficiency. In this paper, we propose a fuzzy-based filtering nodes assigning method for wireless sensor networks to cope with these problems. Our simulation results on the proposed method show the effectiveness of energy consumption against false report injection attacks.
