Due to many restrictions, wireless sensor networks (WSNs) offer novel applications and need novel protocol design approaches. Due to the demand for minimal device complexity and low energy consumption (i.e., a long network lifespan), it is necessary to strike a balance between communication and signal/data processing capabilities. This has resulted in a tremendous amount of effort in research, standardisation, and industry investment in this subject during the previous decade. This survey article will provide an overview of wireless sensor network (WSN) technology, major applications and standards, design characteristics of WSNs, and evolutions. The article discusses various unusual applications, such as those involving environmental monitoring, and highlights design ideas; it also includes a case study based on a real-world implementation. The author charts trends and potential evolutions. The IEEE 802.15.4 standard is emphasised, since it offers a wide variety of WSN applications. The performance characteristics of 802.15.4-based networks are shown and described as a function of the WSN's size and the data type to be transferred between nodes.
