The evolution of inexpensive, powerful personal computers, ever-expanding storage capacity, gigabit bandwidth backbones, unique hardware devices and direct portal access has opened a new frontier in distributed computing. Several operating systems have been built in an attempt to harness the vast store of computational power locked in idle personal computers. A distributed operating system (OS)...

Patches to modern operating systems, including bug fixes and security updates, and the reboots and downtime they require, cause tremendous problems for system users and administrators. The aim of this research is to develop a model for dynamic update of operating systems, allowing a system to be patched without the need for a reboot or other service interruption. In this work, a model for dynam...

The emergence of resource constrained embedded systems such as sensor networks has introduced unique challenges for the design and implementation of operating systems. In OS designs for these systems, only partial functionality is required compared to conventional ones, as their code is running on a much more restricted and homogenous platform. In fact, as illustrated by microcontrollers, most ...

The increasing complexity of embedded systems calls for operating systems that are highly specialized and at the same time are made of a number of reusable building blocks. This brings up a conflict as software specialized in supporting a very dedicated case usually cannot be (easily) reused for a different environment. As described in the paper, supporting specialization without abandonment of...
