Wireless Sensor Networks (WSN) are evolving beyond research prototypes towards real world deployments in various application domains. While prior research has resulted in a range of operating systems and associated programming languages, a comprehensive empirical analysis of WSN operating systems is missing from the literature. We address this problem through an empirical study of all actively maintained...
The application of run-time evolvable software stacks promises an increase in the lifetime of wireless sensor network deployments. Besides supporting changing application requirements, said systems allow the underlying platforms to adapt to new environments by replacing system and communication services at runtime. These dynamics across various software layers however complicate the provision of accurate...
Creating and managing applications for Wireless Sensor Networks (WSNs) is complicated by large scale, resource constraints and network dynamics. Reconfigurable component models minimize these complexities throughout the application lifecycle. However, contemporary component based middleware for WSNs is limited by its poor support for distribution. This paper introduces the Loosely-coupled Component...
Wireless Sensor Network (WSN) applications are traditionally developed on a per-case basis, offering very little reusability or extensibility. Any runtime variability in required data quality is at best addressed by parameterization, reconfiguration and rewiring of existing service compositions. These generic mechanisms can be further optimized if the same data is to be provided at various qualities,...
