This book teaches readers how wireless networks work, why some of their properties impact wireless network performance at the application level, and what both network engineers and application developers can do to cope with these challenges. Internet users increasingly rely on wireless access links for diverse tasks such as web browsing, video conferencing, interactive games, and data sharing. Irrespective of how they access the Internet, they expect good performance and a high quality of experience. Unfortunately, wireless access networks are much more challenging to build than wired networks. In wired networks, signals used for communication are contained in a carefully engineered transmission medium. In contrast, wireless signals travel in our physical environment, where the presence of obstacles, interference, and mobility can affect communication. In addition, network performance can differ significantly across physical environments. As a result, the performance of wireless links is often lower and less predictable than that of wired links. The author structured the book according to the layers in the Internet protocol stack, similar to traditional network books. However, rather than presenting a general description of each layer, the focus is on wireless networks and how they differ from wired networks.

Die Weite der sozialen Medien sorgt dafür, dass es keine Kontrolle über den Umfang der Informationen gibt. Solche Situationen stellen eine große Herausforderung für Vertrauen und Sicherheit dar. Wenn es um die Vertrauenswürdigkeit geht, erweist sich die Kategorie der sozialen Netzwerke (SN) als ein großes Risiko in den sozialen Medien. Die vorgeschlagene Studie konzentriert sich auf "Soziale Netzwerke", die damit verbundenen Herausforderungen und schlägt eine Methode vor, um das Vertrauen des Benutzers in das soziale Netzwerk zu bewerten. Ein vertrauenswürdiger ähnlicher Benutzer wird den anderen Benutzern des Ego-Benutzers empfohlen, die eine Freundschaftsanfrage von einem anderen Benutzer erhalten oder die Freundschaftsanfrage an den vertrauenswürdigen ähnlichen Benutzer richten. Das empfohlene Vertrauen wird mithilfe eines SDE-basierten Reputationsmodells und einer Themenmodellierung mit LDA berechnet.

Just as in traditional wireless networks, Medium Access Control (MAC) in Wireless Sensor Networks (WSNs) continues to attract the attention of many researchers. For a variety of proposed medium access solutions, ensuring good throughput while conserving energy is a real challenge. Asynchronous MAC protocols are distinguished by their short cycle time and low communication cost. Recently, Improved Receiver Initiated MAC Protocol (IRI-MAC), a receiver oriented protocol, has been proposed to reduce collisions in RI-MAC by generating a unique Clear Channel Assessment time (CCA_time) per node. In this book, after showing the possibilities of collisions in IRI-MAC, we propose eIRIMAC, an IRI-MAC based Balancing mechanism to improve it. We show that the proposed solution generates a lower probability of collisions, and reduces Idle-listening through a backoff-based balancing mechanism.

Body Sensor Networks (BSN) in medical applications represent a paradigm-shifting approach to healthcare through the integration of wearable sensors on the human body. These networks form a seamless connection between technology and medicine, enabling the continuous monitoring of vital physiological parameters in real-time. Wearable sensors, discreetly positioned, capture essential data such as heart rate, temperature, and movement, providing an uninterrupted stream of information. This capacity for remote patient monitoring revolutionizes healthcare delivery, allowing healthcare professionals to track patients' conditions remotely and intervene promptly when necessary. BSNs excel in early anomaly detection, triggering alerts for critical events and facilitating timely medical attention. With the ability to provide personalized insights through health analytics, these networks empower both individuals and healthcare providers to make informed decisions tailored to specific health patterns. BSN-generated data contributes to research and innovation, driving advancements in disease management, personalized treatment, and medical knowledge. Ultimately, Body Sensor Networks in medical applications embody a transformative leap towards proactive, personalized, and technologically empowered healthcare practices.These networks are composed of an intricate array of wearable sensors, strategically positioned across the body to capture an individual's physiological data in real-time. Through unobtrusive yet highly sophisticated sensors, BSNs continuously monitor vital signs, movement patterns, and other crucial health metrics. This steady stream of data equips healthcare providers with an unprecedented level of insight into a patient's well-being, enabling timely interventions and personalized medical strategies. The potential of BSNs is vast, ranging from remote patient monitoring that transcends geographical boundaries to early detection mechanisms that forewarn of potential health risks. By integrating seamlessly with data analytics, BSNs empower healthcare professionals to decipher patterns, trends, and anomalies, thereby enhancing diagnostics and treatment plans. These networks also fuel the acceleration of medical research, providing a treasure trove of real-world health data for advancements in disease understanding and treatment development. As BSNs become more sophisticated, they hold the promise of transforming healthcare from reactive to proactive, promoting individual well-being, improving patient outcomes, and revolutionizing the medical landscape as we know it.

According to most organizations, the biggest drivers to cloud are elasticity and agility. In other words, it allows you to instantly provision and de-provision resources based on the needs of the business. You no longer have to build the church for Sunday. Once in the cloud, approximately 80% of companies report receiving bills two to three times what they expected. The truth is that while the promise of cloud is that you only pay for what you use, the reality is that you pay for what you provision. The gap between consumption and allocation is what causes the large and unexpected bills. Cost isn't the only challenge. While most organizations report cost being their biggest problem in managing a public cloud environment, you cannot truly separate performance from cost - the two are tightly coupled. If an organization was optimizing for cost alone, moving all applications to the smallest instance type would be the way to go, but no one is willing to take the performance hit. In the cloud, more than ever, cost and performance are tied together. Digital transformation and a rush to the cloud are placing enterprise IT teams under tremendous pressure. While cloud addresses an old pain point - that infrastructure supply is static while application demand is dynamic - matching demand with supply in real-time across multiple metrics and dimensions requires more decisions than any human being can make. Hybrid cloud estates are unbelievably complex. There are millions of configuration options for EC2 instances alone, AWS has 212 additional products and services and Microsoft lists over 600 Azure services (as of May 2020). This is simply too much complexity for the average IT team to manage and, as a result, many organizations that kicked off digital transformation initiatives with high hopes end up watching innovation grind to a halt while the IT team struggles just to keep the lights on.
