Nowadays, virtualization is a technology that applied for sharing the capabilities of physical computers by splitting resources among OSs. The concept Virtual Machines (VMs) started back in 1964 with IBM project called CP/CMS system. Currently, there are several techniques can be used supporting execution entire operating systems. We classify from OS view. First, we discuss two executes modified guest OSs: system-level and para-virtualization. Second, unmodified binary translation hardware...

Wireless sensor networks are gaining greater attention from the research community and industrial professionals because these small pieces of "smart dust" offer great advantages due to their size, low power consumption, easy integration support for "green" applications.

Because battery-powered nodes are required in wireless sensor networks and energy consumption represents an important design consideration, alternate sources needed to provide more effective optimal function. The main goal of this work is present harvesting network platform, the Open Wireless Sensor node (WiSe). implementation solar powered platform described including hardware architecture, firmware, a POSIX Real-Time Kernel. A sleep wake up strategy was implemented prolong lifetime...

A current trend in the development and implementation of industrial applications is to use wireless networks communicate system nodes, mainly increase application flexibility, reliability portability, as well reduce cost. However, nondeterministic concurrent behavior distributed systems makes their analysis design complex, often resulting less than satisfactory performance simulation test bed scenarios, which caused by using imprecise models analyze, validate these systems. Moreover, there...

Modern industrial automation supported by Cyber–Physical Systems (CPSs) requires high flexibility, which is achieved through increased interconnection between modules. This introduces a layer of symmetry into the design and operation CPSs, balancing distribution tasks resources across system streamlining flow information. However, this adaptability also exposes control systems to security threats, particularly novel communication links that are vulnerable cyberattacks. Traditional strategies...
