Abstract |
Wireless sensor networks (WSNs) can be generally easily compromised by attackers since the networks are deployed in hostile environments. The attackers can inject a false report into the networks or fabricate MACs (message authentication codes) on real reports through compromised nodes. The attacks break down the networks as a result of the dissipation of energy or the interception of the message. Li and Wu proposed the PVFS (probabilistic voting-based filtering scheme) in order to protect against this type of attack. In the PVFS, determining the number of votes is very important since it determines the trade-off between the security level and the energy consumption. In this paper, we propose an EFSP (En-route Filtering Scheme based on Priority) to control the number of votes. The EFSP determines priorities through the fuzzy rule-based system. Each cluster head receives priority from the base station and then the cluster head attaches a specified number of votes to the report according to the priority. We demonstrate the efficiency of our EFSP through the simulation results. |
