Wireless Sensor Networks (WSNs) detect and report interesting events when they occur in the target region. These networks are vulnerable to security breach due to wireless communication and lack of infrastructure. In sinkhole attacks, an attacker attracts network traffic by forging or replaying routing messages through compromised nodes. Thus attracted(More)
In many sensor network applications, sensor nodes are deployed in unattended environments , and hence are vulnerable to physical attacks, potentially compromising the node's cryptographic keys. False sensing reports can be injected through compromised nodes, which can lead to not only false alarms but also the depletion of limited energy resources in(More)
