In this paper we address the problem of robustly estimating the position of randomly deployed nodes of a Wireless Sensor Network (WSN), in the presence of security threats. We prop...
Hierarchical wireless sensor networks (WSNs) have been shown to improve system performance, reduce messages redundancy, and economize energy. However, due to the characteristics o...

Key establishment in sensor networks is a challenging problem because asymmetric key cryptosystems are unsuitable for use in resource constrained sensor nodes, and also because th...
In many applications of wireless sensor networks (WSN), sensors are deployed un-tethered in hostile environments. For locationaware WSN applications, it is essential to ensure tha...
This paper describes an INtrusion-tolerant routing protocol for wireless SEnsor NetworkS (INSENS). INSENS securely and efficiently constructs tree-structured routing for wireless ...
