An Information Driven Sensornet Architecture

Most sensor networks do not support QoS or heterogeneity. As a result, current sensor networks are not suited for next-generation applications, such as wireless building automation, process control or medical applications. In this paper, we present an alternative architecture wherein the system is responsible for packet creation and packet manipulation. To support QoS, energy-efficiency and heterogeneity, the system intelligently combines information exchanges from multiple network protocols in a single packet. We demonstrate that this approach is better suited for very demanding applications and prove that this approach is much more scalable, in terms of memory requirements, than tradition system architectures.
