Abstract
Most sensor network research and software design has been guided by an architectural principle that permits multi-node data fusion on small-form-factor, resource-poor nodes, or motes. We argue that this principle leads to fragile and un-manageable systems and explore an alternative. The Tenet architecture is motivated by the observation that future large-scale sensor network deployments will be tiered, consist-ing of motes in the lower tier and masters, relatively un-constrained 32-bit platform nodes, in the upper tier. Masters provide increased network capacity. Tenet constrains multi-node fusion to the master tier while allowing motes to pro-cess locally-generated sensor data. This simplifies applica-tion development and allows mote-tier software to be reused. Applications running on masters task motes by composing task descriptions from a novel tasklet library. Our Tenet im-plementation also contains a robust and scalable network-ing subsystem for disseminating tasks and reliably deliver-ing responses. We show that a Tenet pursuit-evasion applica-tion exhibits performance comparable to a mote-native im-plementation while being considerably more compact.
