In this paper, we propose a novel, cluster-based energy balancing scheme. We assume the existence of a fraction of “strong” nodes in terms of abundant storage, computing and co...
The node localization problem in Wireless Sensor Networks has received considerable attention, driven by the need to obtain a higher location accuracy without incurring a large, p...
—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 presents a sentry-based approach to power management in wireless sensor networks for applications such as intruder detection and tracking. To minimize average power cons...
Key management is one of the fundamental building blocks of security services. In a network with resource constrained nodes like sensor networks, traditional key management techni...
