The authors of [32] have proposed an IoT-based asset tracking systems for a health center named LoCATE—Localization of Health Center Assets Through an IoT Environment. LoCATE is a near real-time tracking system based on IoT for tracking patients, medical staff, and medical devices in a health center using 802.11 WIFI infrastructure. The system continuously logs the real-time location data of patients, medical staff, and all the devices into the cloud using which the administrators can find the location of patients, doctors, or devices with help of a mobile or web application. LoCATE also analyzes the collected data and exposes the inefficiencies in the workflow of the health center. The hardware used in LoCATE is Raspberry Pi equipped with a USB wireless adaptor capable of monitoring 802.11 wireless packets. The software used in LoCATE includes EC2 cloud instance running on AWS utilizing the Ubuntu server operating system. To build the user interface of web application, the application framework used is LAMP. To sniff the network traffic TShark utility is used in LoCATE. In summary, LoCATE is a low-cost asset tracking system designed using cloud, IoT, and 802.11 technologies which include the benefits of flexibility, scalability, and improved health center work operations when compared to traditional systems.

One of the most popular Linux distributions, Ubuntu 16.04.2 LTS (Xenial Xerus) was used as a host operating system [16]. It is based on Debian architecture and it is open source with both community and professional support. Ubuntu is suitable for both desktop and server use. The current Ubuntu release supports Intel x86 (IBM-compatible PC), AMD64 (x86–64), ARMv7, ARMv8 (ARM64), IBM POWER8, IBM zSeries (zEC12/zEC13) and PowerPC architectures. It also supports virtual file system feature [17], which represents an object-oriented form of file system implementation allowing user to the identical access to all files, regardless of file system that these files belong to. Ubuntu includes a wide range of software, covering every standard desktop application from word processing and spreadsheet applications, browsers, web server software, email software, programming languages and tools and even games. Many additional software packages are available from the built in Ubuntu Software Center. Ubuntu operates under the GNU General Public License and all software installed on Ubuntu is free software. In Ubuntu, emphasis has been also put on security, so developers are trying to make Ubuntu secure out-of-the-box. To achieve that, users programs run with low privileges, most network ports are closed to prevent hacking and disk drive encryption is also available.

Principally, a ROS-VM is composed by: An operating system (Ubuntu).Robot Operating System (ROS).Robots APIs.A set of Packages: A package, which is developed for robotic tasks performance, contains source code for ROS nodes. These codes are encapsulated, reused, and interoperable robotic services. They are proposed as web services.
