Sensor Network Architecture and Layering: *Sensor network exists typically to do one thing (All custom built.) *Expensive to pretend sensor is a general purpose computer *Reduce costs and improve performance by eliminating unneeded functionality *Layering is original sin of networking *We have little idea how else to build a network *While we gain experience, we maintain most of layering, with a few optimizations. Conclusions: *Sensor network doing event detection studied. Trying to optimize (a) accuracy of detection, and (b) network lifetime. *Cross-layer optimizations: achieved through routing metric: routing interacts with data aggregation (application) and with battery level (physical layer) *Routing appears to be a convenient place for layers to interact.
