Wireless sensor networks are usually deployed in a way “once deployed, never changed”. The actions of sensor nodes are either pre-scheduled inside chips or triggered to respon...
Most of the routing protocols in wireless ad hoc networks, such as DSR, assume nodes are trustworthy and cooperative. This assumption renders wireless ad hoc networks vulnerable to...
—In an adversarial environment, various kinds of security attacks become possible if malicious nodes could claim fake locations that are different from where they are physically ...
This paper introduces a new approach that addresses data contamination problems from attacks in unattended wireless sensor networks. We propose a sliding-window based spatio-tempo...
— Node compromise is a serious threat in wireless sensor networks, as it enables an adversary to perform various attacks. Many security schemes exploit the redundancy of many wir...
