A Low-Complexity Algorithm for Intrusion Detection in a PIR-Based Wireless Sensor Network
• Investigated the problem of detecting a human intruder in the presence of clutter arising from wind-blown vegetation in a passive infra-red (PIR) based wireless sensor network (WSN).
• Proposed a low-complexity algorithm based on a combination of Haar Transform (HT) and Support Vector Machine (SVM) based training. Extensive field testing of the algorithm was done. The algorithm exhibited a very good performance.

Analytical Model For Intruder Signature
• Goal was to come up with a model for the intruder signature.
• Provided a closed-form expression for a good approximation to the intruder waveform.
• Developed, for the first time in literature, a model for the PIR sensor’s signature.
• Used this to determine how to optimally place multiple sensing nodes so as to estimate the path of the intruder in motion.
