This paper proposes an innovative battery-sensing intrusion protection system (B-SIPS) for mobile computers, which alerts on power changes detected on small wireless devices. These hosts are employed as sensors in a wireless network and form the basis of the "Canary-Net" 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 and 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
