This book presents an in-depth study on the recent advances in Wireless Sensor Networks (WSNs). The authors describe the existing WSN applications and discuss the research efforts being undertaken in this field. Theoretical analysis and factors influencing protocol design are also highlighted. The authors explore state-of-the-art protocols for WSN protocol stack in transport, routing, data link, and physical layers. Moreover, the synchronization and localization problems in WSNs are investigated along with existing solutions. Furthermore, cross-layer solutions are described. Finally, developing areas of WSNs including sensor-actor networks, multimedia sensor networks, and WSN applications in underwater and underground environments are explored. The book is written in an accessible, textbook style, and includes problems and solutions to assist learning. Key Features: The ultimate guide to recent advances and research into WSNsDiscusses the most important problems and issues that arise when programming and designing WSN systemsShows why the unique features of WSNs – self-organization, cooperation, correlation -- will enable new applications that will provide the end user with intelligence and a better understanding of the environmentProvides an overview of the existing evaluation approaches for WSNs including physical testbeds and software simulation environmentsIncludes examples and learning exercises with a solutions manual; supplemented by an accompanying website containing PPT-slides.Wireless Sensor Networks is an essential textbook for advanced students on courses in wireless communications, networking and computer science. It will also be of interest to researchers, system and chip designers, network planners, technical mangers and other professionals in these fields.

This book offers the most suitable methods of applying Low-Power Wide-Area Network (LPWAN) technology to conceptual works and/or research studies. For instance, existing IoT protocols such as CoAP and MQTT are complemented by LPWAN to provide better service quality (QoS) to enable the notion of "sensor as a service" to endpoint users which is demonstrated in this book. LPWAN is a new enabling technology for IoT, filling the gap that existed between the legacy network technologies (WLAN, LAN, PAN) in terms of power, range, and data rates. It is also an alternative solution to implementations of IoT via cellular (4G/5G/6G) technologies, as it operates on the ISM band and also provides long-term battery life. Due to the several advantages, it brings, LPWAN raises high enthusiasm for many stakeholders of IoT. However, there still exist many research challenges to be tackled within this technology.  As such this book aims at shedding light on those research problems.Moreover, practical users can also benefit from this book: Emergency response teams can leverage IoT systems with the extended communications-range capability provided by LPWAN technology. Moreover, machine-to-machine (M2M) and thing-to-thing (T2T) communications also benefit from this notion, as well as the Social IoT (SIoT) concept, owing to the “low-power” consumption advantage that is brought up by LPWAN technologies, e.g., 10 years battery lifetime projection for the LoRaWAN end-devices is very promising. Eventually, this proposed book aims at covering all aspects of LPWANs, from A to Z, theoretical aspects, hardware platforms and technologies, along with applications, opportunities, and, finally, challenges.Cyber-attacks and incidences are on the rise within the last decade, especially cases in large corporates and critical infrastructures have shown that cybersecurity should become one of the important pillars of computer network infrastructures as well as any kind of relevant technology being introduced. As such, cybersecurity is bringing attention not only from practitioners and academicians but also from other parties such as media, politicians, etc. Eventually, to reflect this important point of view, this book includes three chapters to investigate various aspects of LPWAN cybersecurity.Researchers working in wireless communications technologies and advanced-level students taking courses in electrical engineering or computer science will benefit from this book as a reference. Professionals working within this related field will also want to purchase this book.
