A wireless sensor network (WSN) is a collection of self-organized sensor nodes. WSNs have been a popular research topic for a long time. With the advances in the Internet of Things, this research area still attracts many people. This book explains fundamental concepts of wireless sensor networks. It is a good book to learn about the principles, definitions, and applications of WSNs.

There are eight chapters in the book. The first chapter is an introduction to WSNs. In the second chapter, the seven-layer protocol is presented. The third chapter lists the applications of WSNs such as healthcare and environmental monitoring. Chapter 4 is about the transport protocols of WSN such as Tiny TCP/IP. Chapter 5 informs readers about famous testbeds for testing WSN research. This information is very useful because it is hard to create a realistic test environment for sensor networks. Chapter 6 covers simulators such as ns-3. Chapters 7 and 8 are about sensor manufacturers. These chapters contain all the essential information about sensors.

WSNs face many challenges: lack of centralized network administration, low data transmission capacity, low bandwidth, lack of connectivity, limited power supply, and dynamic network topology. These challenges make WSNs a good research area. This book is a good source for students, researchers, and industry professionals. It is useful for learning the basics of WSNs and establishing a strong background on the subject.
