Enix is a lightweight dynamic operating system for tightly constrained platforms for wireless
sensor networks (WSN). Enix provides a cooperative threading model, which is applicable to …

In this paper we examine the current state of the art in WSN operating systems in terms of
their general programming models and runtime reprogramming features. While all OSs …

TinyOS has been adopted by thousands of developers worldwide, on many platforms, for a
broad range of wireless sensor networks. Its communication-centric design and modular …

Many threads packages have been proposed for programming wireless sensor platforms.
However, many sensor network operating systems still choose to provide an eventdriven …

Often software for wireless sensor networks (WSNs) is developed using a specific event
based operating system (OS) such as TinyOS. However, this requires steep learning curve …

This paper presents the design principles, implementation, and evaluation of the RETOS
operating system which is specifically developed for micro sensor nodes. RETOS has four …

The development of a reliable large-scale wireless sensor network (WSN) is very difficult
because of resource constraints, energy budget, and demanding application requirements …

Sensor network nodes exhibit characteristics of both embedded systems and general-
purpose systems. They must use little energy and be robust to environmental conditions …

The development of a modern sensor network is difficult because of the long-term
unattended operation mode, diverse application requirements, and stringent resource …

Wireless sensor networks are composed of large numbers of tiny networked devices that
communicate untethered. For large scale networks, it is important to be able to download …
