485 Hibler, Michael J.Interface and execution models in the fluke kernelWe have defined and implemented a new kernel API that makes every exported operation either fully interruptible and restartable, thereby appearing atomic to the user. To achieve interruptibility, all possible states in which a thread may become blocked for a "long" time are completely representable ...Fluke kernel; Interruptibility1998
486 Regehr, JohnInterface contracts for TinyOSTinyOS applications are built with software components that communicate through narrow interfaces. Since components enable fine-grained code reuse, this approach has been successful in creating applications that make very efficient use of the limited code and data memory on sensor network nodes.
