Poster Abstract: Threads for the Programmer, Events for the Machine

Executive Summary

Major motes operating systems like TinyOS or Contiki rely on an event-driven programming paradigm. While the use of events allows for limiting memory usage on resource-constrained motes, it may also hamper the development and debugging of applications, especially as their complexity increases. Several authors also investigated the possibility of introducing threads to mote programming. However, the proposed solutions all induce runtime overhead which is inherent to the thread paradigm. In contrast, protothreads combine the benefits of both paradigms by providing thread semantics to the programmer while using events at runtime.
