Abstract
Many Wireless Sensor Network (WSN) applications are composed of a mixture
of deployed devices with varying capabilities, from extremely constrained 8-bit ``Motes''
to less resource-constrained 32-bit ``Microservers''.
EmStar is a software environment for developing and deploying complex WSN
applications on networks of 32-bit embedded Microserver platforms, and integrating
with networks of Motes.
EmStar consists of libraries that
implement message-passing IPC primitives, tools that support
simulation, emulation, and visualization of live systems, both real
and simulated, and services that support networking,
sensing, and time synchronization. While EmStar's design has favored
ease of use and modularity over efficiency, the resulting increase in
overhead has not been an impediment to any of our current projects.
