The basic operation in such a network is the efficient gathering and transmission of sensed data to a base station for advance processing. The life of such a sensor system is the time during which the authors can gather information from all the sensors to the base station. A fundamental challenge in data gathering is to maximize the system lifetime, given the energy constraints. As sensor networks are being all the time more deployed in decision-making. The authors introduce efficient tools for provenance verification method and reconstruction method at the base station with the functionality to detection packet drop attacks or by malicious data forwarding nodes.
