Abstract:
Sensor networks are used for simple monitoring applications, but also for complex applications, such as wireless building automation or medical assistance. Current layered architectures do not support the dynamic and heterogeneous nature of these networks. Therefore, we present an alternative architecture that decouples protocol logic and packet representation. Using this system, multiple information exchanges are automatically combined in a single packet. In addition, the system dynamically selects the most optimal network protocols and supports systemwide quality-of-service. Thus, our architecture is better suited for next-generation applications. We illustrate our architecture with several code examples, and prove that our architecture is much more scalable, in terms of memory requirements, energy requirements and processing overhead, than tradition system architectures.
