Contiki - a lightweight and flexible operating system for tiny networked sensors

A framework for service provisioning in virtual sensor networks

“…Moreover, running one or more applications that are not supported by the host OS, which is the most reasonable use of full platform virtualization, is a much more infrequent case in sensor nodes than traditional PCs. Up to date most OSs are built under the event-driven framework (e.g., TinyOS [5], Contiki [6]). A traditional thread-based approach is supported by the kernel of the MANTIS OS [7].…”

Experience with Safe Dynamic Reconfigurations in Component-Based Embedded Systems

“…Contiki [9,8] is a reconfigurable modular operating system for networked sensors. A Contiki system uses a flat module architecture, a module is the unit of reconfiguration.…”

“…TinyOS [20], Contiki [9], SOS [17], Mantis [3], FlexCup [25], either do not support dynamic reconfiguration (TinyOS), or provide low-level mechanisms for dynamic reconfiguration -typically dynamic linking of modules or components -that do not alleviate the issues involved in programming safe reconfigurations.…”

Improving the Energy Efficiency of the MANTIS Kernel

“…One example of an operating system that tries to bridge the gap is Contiki [3]. Contiki is an event-based sensor network operating system that includes a threaded library that can be optionally compiled to facilitate multi-threaded applications.…”

“…Thus TinyOS still achieves preemption without sacrificing the lightweight scheduling characteristics. In summary, the research focus of [3,4,5] is to minimize the processing overhead of a multi-threaded system, by isolating only the processes that require multi-threaded capabilities. However no effort is made to reduce the overhead of the multi-threaded processes.…”
