“…There are many techniques to protect a network against attackers from outside, for example firewalls [15]. But when the network uses wireless transmission, an attacker that is close enough to the network can eavesdrop, it can insert malicious packets, or it can simply jam the wireless medium and distort any other transmission, this way challenging reliable and timely transmission.…”

Abstract-In this paper we discuss a selection of promising and interesting research areas in the design of protocols and systems for wireless industrial communications. We have selected topics that have either emerged as hot topics in the industrial communications community in the last few years (like wireless sensor networks), or which could be worthwhile research topics in the next few years (for example cooperative diversity techniques for error control, cognitive radio/opportunistic spectrum access for mitigation of external interferences).Index Terms-Cognitive radio, IEEE 802154, industrial-QoS, spatial and cooperative diversity, ultra-wideband, wireless sensor networks, ZigBee.

“…Just like the previously mentioned stunnel, can the Secure SHell (SSH) protocol also create tunnels for higher layer applications by implementing a connection specific port forwarding [22]. Due to the use of TCP SSH is also not suited for the transport of delay critical data and usually not considered for realizing generic VPNs.…”

Virtual private networks (VPN) offer a secure data exchange over public networks. Despite being cheaper than leased lines, growing sizes and dynamic behavior of VPN nodes, e.g., for mobility or reasons of denial-of-service-attacks, make a manual configuration of large, dynamic VPN expensive.Consequently, a number of different VPN auto-configuration approaches have been invented and partially deployed over the last decade. This article identifies a comprehensive set of objectives to be fulfilled by IP-based VPN auto-configuration, explains and groups mechanisms, and analyzes their strengths and weaknesses with regards to the objectives. Finally, it identifies potential future directions of autonomous VPN deployment.

Wireless sensor networks are a fascinating and challenging area of research and a key enabler for new applications involving smart objects interacting with the physical environment. Example applications are building automation, facility management, intelligent agriculture and environmental monitoring. Wireless sensor networks have unique properties which make the design of protocols and applications especially challenging: a finite energy budget, limited processing capabilities, scaling requirements coming from high node densities, the need for intelligent local collaboration, in-network processing and many more. This article gives an introduction to the concept of sensor networks and discusses important characteristics of sensor node and sensor network architectures. These characteristics have profound impact on the design of protocols, as will be exemplified on medium access control (MAC) protocols for sensor networks. Finally, we discuss some of the research challenges which in our opinion are key to bring wireless sensor networks into more real applications.Keywords: wireless sensor networks; energy-efficiency; sensor node architecture Drahtlose Sensornetze: Konzept, Herausforderungen und Methoden. Drahtlose Sensornetze sind ein faszinierendes und herausforderndes Forschungsgebiet und erlauben die Gestaltung neuartiger Anwendungen, in denen smarte Objekte mit unserer physikalischen Umwelt interagieren. Mö gliche Anwendungen von Sensornetzen sind Gebä udeautomatisierung, Facility Management, Landwirtschaft und Umweltbeobachtung. Drahtlose Sensornetze haben einzigartige Eigenschaften, die den Entwurf und die Implementierung von Protokollen und Anwendungen zu einer besonderen Herausforderung machen: ein begrenztes Energiebudget, beschrä nkte Rechenkapazitä ten und Speicherressourcen, große Knotendichten, der Bedarf nach intelligenter Zusammenarbeit zwischen Sensorknoten, in-network-processing und viele mehr. Der vorliegende Artikel gibt eine Einfü hrung in das Konzept drahtloser Sensornetze und stellt wichtige Merkmale von Sensorknoten-und Netzwerkarchitekturen vor. Diese Merkmale haben erheblichen Einfluss auf den Entwurf von Protokollen, was am Beispiel von Mediumzugriffsprotokollen exemplarisch dargestellt wird. Schlussendlich werden noch einige Herausforderungen fü r die weitere Forschung diskutiert, mit besonderem Augenmerk auf Probleme, die fü r einen weitverbreiteten praktischen Einsatz von Sensornetzen noch befriedigend gelö st werden mü ssen. Schlü sselwö rter: drahtlose Sensornetze; Energieeffizienz; Architektur der Sensorknoten
