Overview

The ability of wireless sensor networks (WSNs) to support a practically endless variety of human activities places them among the most rapidly developing domains of technology with a continuously growing range of applications. On the other hand, the utilization of WSNs is obstructed because of not only the limited resources of sensor nodes in terms of energy supply, memory, and processing but also the inborn restrictions of wireless communications regarding power, speed, and the capacity of communication channels and their vulnerability to interferences and intrusion. Thus, numerous challenges arise on the subject of WSNs. This reprint aims to immerse the reader in the research works related to the state-of-the-art standards, experimentations, implementations, applications, new research proposals, and case studies regarding Wireless Sensor Networks, and we attracted the interest of many researchers associated with the previous topics. Finally, ten high-quality papers were selected for publication after a double-blind review process.
