Battery-Sensing Intrusion Protection for Wireless Handheld Computers Using a Dynamic Threshold Calculation Algorithm for Attack Detection

This paper proposes a pioneering battery-sensing intrusion protection system (B-SIPS) for mobile computers, which alerts on power changes detected on small wireless devices, using an innovative dynamic threshold calculation algorithm. B-SIPS enabled hosts are employed as sensors in a wireless network and form the basis of the intrusion detection system (IDS). This detection capability is scalable and complementary with existing commercial and open system network IDSs. B-SIPS implementation correlates device power consumption with IEEE 802.11 Wi-Fi and 802.15.1 Bluetooth communication activity. Irregular and attack activity is detected and reported to the intrusion detection engine for correlation with existing signatures in a database and for forensic investigation by a security manager
