چکیده
With the proliferation of sensor networks and sensor network applications, the overall complexity of such systems is continuously increasing. Sensor networks are now heterogeneous in terms of their hardware characteristics and application requirements even within a single network. In addition, the requirements of currently supported applications are expected to change over time. All of this makes developing, deploying, and optimizing sensor network applications an extremely difficult task. In this paper, we present the architecture of TinyCubus, a flexible and adaptive crosslayer framework for TinyOS-based sensor networks that aims at providing the necessary infrastructure to cope with the complexity of such systems. TinyCubus consists of a crosslayer framework that enables optimizations through crosslayer interactions, a configuration engine that distributes components efficiently by considering the roles of the sensor nodes and provides support to install components dynamically, and a data management framework that selects and adapts both system and data management components. Finally, relevant research challenges associated with the development of each framework are identified and discussed in the paper. Zusammenfassung Mit der zunehmenden Verbreitung von Sensornetzen und Sensornetzanwendungen wächst die Komplexität solcher Systeme ständig an. Sensornetze sind nun in Bezug auf ihre Hardware-Eigenschaften und Anwendungsanforderungen häufig sogar in einem einzelnen Netz heterogen. Außerdem wird erwartet, dass die Anforderungen der Anwendungen sich mit der Zeit ändern. Dies alles erschwert es, Sensornetzanwendungen zu entwickeln, einzusetzen und zu optimieren. In diesem Artikel stellen wir die Architektur von TinyCubus vor, einem flexiblen und adaptiven Cross-Layer Framework für TinyOS-basierte Sensornetze, dessen Ziel es ist, die notwendige Infrastruktur bereitzustellen, um die Komplexität solcher Systeme zu unterstützen. TinyCubus besteht aus einem Cross-Layer-Framework, das Optimierungen durch Cross-Layer-Interaktionen ermöglicht, einer Configuration-Engine, die Komponenten effizient durch die Beachtung der Rollen der Sensorknoten verteilt und die dynamische Installation von Komponenten erlaubt, und einem Data-Management-Framework, das sowohl Systemals auch Datenverwaltungskomponenten dynamisch auswählt und adaptiert. Schließlich werden in diesem Beitrag relevante Forschungsprobleme, die die Entwicklung der einzelnen Teile betreffen, bestimmt und diskutiert.

متن کاملCross Layer Security Framework for Wireless Sensor Networks
Since the data collected by the nodes of WSN are sensitive and vulnerable to attack, there’s a need of making the Wireless Sensor Networks (WSN) immune to attacks. Most of the researchers have come up with security solution to WSN based on layered approach. Layered approach has noticeable flaws like ‘redundant’ security or ‘inflexible’ security solutions. In this paper a new security scheme is ...
