Abstract. In this paper, we propose a novel hierarchical routing protocol for a large wireless sensor network (WSN) wherein sensors are arranged into a multi-layer architecture wit...
An important problem in wireless ad hoc and sensor networks is to select a few nodes to form a virtual backbone that supports routing and other tasks such as area monitoring. Prev...
Abstract—Spectrum sensing is one of the key enabling technologies in Cognitive Radio Networks (CRNs). In CRNs, secondary users (SUs) are allowed to exploit the spectrum opportuni...
