This article analyzes the connectivity of multihop radio networks in a log-normal shadow fading environment. Assuming the nodes have equal transmission capabilities and are randoml...
Indoor localization is of great importance for a range of pervasive applications, attracting many research efforts in the past decades. Most radio-based solutions require a proce...
Wireless Sensor Networks (WSNs) may be deployed in hostile or inaccessible environments and are often unattended. In these conditions securing a WSN against malicious attacks is a...
—In this paper, an information grouping paradigm for QoI in sensor networks is introduced. First, a definition of QoI is presented by analyzing the ITU’s definition of QoS. T...
