: Wireless sensor networks require energy efficient routing protocols owing to limited resource on the sensor node. In this paper, we develop optimal distance geographic routing (O...
—We present the derivation of a novel metric for the performance prediction of Wireless Sensor Networks (WSNs). In particular, the metric can be applied in, for example, monitori...
This paper investigates the energy cost of control packets in schedule-based medium access control protocols in wireless sensor networks. Control packets can be useful not only to ...
– In this paper, we present a comprehensive study on the design of secure and survivable wireless sensor networks (WSNs). Our goal is to develop a framework that provides both se...
We address security solutions to protect the communication of the wireless components of a home health care system. We analyze especially the problem of exchanging secrets to sati...
