As the application scope of wireless sensor network (WSN) grows at an amazing rate, the security issue of WSN is becoming increasingly important. Considering a distinct way to address the security problem rather than using the two most common methods which are data encryption and authentication, in this paper, we enhance an off-the-shelf data clustering based method called GSD by focusing on preprocessing RSSI and LQI data of WSN with sliding window and statistic methods for intrusion detection. Our results show that by preprocessing the RSSI and LQI data with the proposed Moving Average Variance method, GSD algorithm performs better in intrusion detection for WSNs.
