LoRaWAN is a LPWAN (Low Power Wide Area Network) technology used in a large variety of Internet of Things (IoT) applications. The paper addresses the security concerns of data protection and data privacy in sensor networks that make use of the LoRaWAN (Long-Range Wide Area Network) protocol specification. In this context, this paper performs an in-depth analysis of the security aspects in LoRaWAN...
Indoor localization and navigation using wireless sensor networks is still a big challenge if expensive sensor nodes are not involved. Previous research has shown that in a sparse distributed sensor network the error distance is way too high. Even room accuracy can not be guaranteed. In this paper, an easy-to-use generic positioning framework is proposed, which allows users to plug in a single or...
Computer-enhanced smart environments, distributed environmental monitoring, wireless communication, energy conservation and sustainable technologies, ubiquitous access to Internet-located data and services, user mobility and innovation as a tool for service differentiation are all significant contemporary research subjects and societal developments. This position paper presents the design of a hybrid...
Smart embedded objects such as sensors and actuators will become an important part of the Internet of Things. With recent technologies, it has now become possible to deploy a sensor network and interconnect it with IPv6 Internet. However, several manual configuration steps are still needed to integrate a sensor network within an existing networking environment. In this paper we describe a novel self-organization...
In a future internet of things, an increasing number of every-day objects will be connected with each other. These objects can be very diverse in terms of their network protocols and communication technologies. As more resource constrained devices such as sensor networks and PDAs are added to our environment, supporting efficient communication between these heterogeneous devices becomes a key challenge...
