In this thesis we present and operating system and three generations of a hardware
platform designed to address the needs of wireless works. Our operating
system, called TinyOS uses an event based execution model to provide support for fine-
grained concurrency and incorporates a highly ponent model. TinyOS
enables us to use a hardware architecture that has a single processor time shared between
both application and protocol processing. We show how a virtual partitioning of
computational resources not only leads to efficient resource utilization but allows for a
rich interface between application and protocol processing. This rich interface, in turn,
allows developers to exploit application munication protocols that
significantly improve system performance.
The hardware platforms we develop are used to validate a generalized architecture
that is technology independent. Our general architecture contains a single central
controller that performs both
