Secure Wireless Sensor Networks

Sensor networks are ideal candidates for a wide rangeof applications such as monitoring of criticalinfrastructures data acquisition in hazardousenvironments and military operations. It isnecessary to guarantee the security and resilience ofsensor networks (as well as their applications) asthey become more and more popular. Despite manysecurity schemes have been proposed to protectbuilding blocks such as routing and key managementsome other building blocks (e.g. mobile sink andtime synchronization) are largely ignored. This booktherefore provides security building blocks forsensor networks and develops a potential killerapplication for sensor networks. The two proposedsecurity building blocks will help the sensornetworks tolerate mobile sink compromises and beresilient against attacks on the timesynchronization respectively. SVATS asensor-network-based vehicle anti-theft system isdesigned to address the limitations of high costhigh false-alarm rate and the easy disablingdrawbacks of the current vehicle theft tracking andalarming systems. This system can detect vehicletheft within seconds and track stolen vehicles aswell.
