Power Supply for Wearables with Task Offloading Capabilities
Task-offloading approaches can be efficiently combined with energy harvesting to address the issue of insufficient battery capacity and limited computation resources in IoMT devices and consequently increase the operating time of wearable devices. This is referred to as joint energy harvesting and task offloading. Using this technology, users can extract energy, convert it into useful energy, store it in the appropriate energy-storage device, and use that energy to perform the corresponding local computing and offloading tasks.

Safeguarding Traditional Crafts in Europe
This entry discusses the challenge of safeguarding crafts in Europe. Safeguarding is defined herein as the systematic process of understanding, representing, preserving, and valorizing crafts following the recommendations of UNESCO and the UN-World Tourism Organization. The abovementioned challenges are discussed through a multidisciplinary prism starting from the scientific challenges in the information and communication technologies sector and expanding the discussion to ethical, legal, and policy-making measures and recommendations to safeguard crafts as a form of tangible and intangible cultural heritage but also as a source of growth and impact for the communities that practice them. To this end, the role of education and training for craft preservation is discussed, considering that the declining number of practitioners and apprentices is considered today the main threat to their preservation.

Specifications of 5G Cell Search
5G Cell Search (CS) is the first step for user equipment (UE) to initiate communication with the 5G node B (gNB) every time it is powered ON. In cellular networks, CS is accomplished via synchronization signals (SS) broadcasted by gNB. 5G 3rd generation partnership project (3GPP) specifications offer a detailed discussion on the SS generation at gNB, but a limited understanding of their blind search and detection is available.

Topology Designs for Data Centers
The adoption of simple network topologies allows for an easier way to forward packets. On the other hand, more complex topologies may achieve greater performance, although network maintenance may become harder. Hence, a balance between performance and simplicity is a convenient point when choosing a data center design. Therefore, some topology designs for data centers are going to be proposed; these are classified into tree-like and graph-like architectures. With respect to the former, a hierarchical switching layout interconnects all nodes, thus showing the form of an inverted tree within multiple roots, where nodes are the leaves of such a tree. Regarding the latter, nodes are directly interconnected to each other, hence no switch is involved in the design.

Fog-Based IoT Platform Performance Modeling and Optimization
A fog-based IoT platform model involving three layers, i.e., IoT devices, fog nodes, and the cloud, was proposed using an open Jackson network with feedback. The system performance was analyzed for individual subsystems, and the overall system was based on different input parameters. Interesting performance metrics were derived from analytical results. A resource optimization problem was developed and solved to determine the optimal service rates at individual fog nodes under some constraint conditions.

Sensor Network Environments
New technologies have driven the rise of what is being termed as the fourth industrial revolution. The introduction of this new revolution is amalgamating the cyber and physical worlds, bringing with it many benefits, such as the advent of industry 4.0, the internet of things, cloud technologies and smart homes and cities. These new and exciting areas are poised to have significant advantages for society; they can increase the efficiency of many systems and increase the quality of life of people. However, these emerging technologies can potentially have downsides, if used incorrectly or maliciously by bad entities. The rise of the widespread use of sensor networks to allow the mentioned systems to function has brought with it many security vulnerabilities that conventional “hard security” measures cannot mitigate. It is for this reason that a new “soft security” approach is being taken in conjunction with the conventional security means. Trust models offer an efficient way of mitigating the threats posed by malicious entities in networks that conventional security methods may not be able to combat.
