Dear Colleagues,

In an era defined by rapid technological advancement, the Internet of Things (IoT) has emerged as a transformative force, reshaping the way we interact with the world around us. At the heart of this technological revolution lies the seamless integration of smart applications within IoT ecosystems, which are interconnected through Wireless Sensors and Actor Networks (WSAN). This convergence of cutting-edge technologies has not only accelerated the development of innovative solutions but has also redefined our understanding of connectivity, efficiency, and automation in various domains, from home automation to industrial processes, healthcare, and environmental monitoring.

The concept of IoT revolves around the interconnection of everyday objects, devices, and systems through the Internet, enabling them to collect, transmit, and exchange data in real time. Wireless sensors play a pivotal role in this network, as they are the eyes and ears of the IoT, collecting data from the physical world. These sensors are equipped with a multitude of capabilities, including data acquisition, processing, and communication, making them the building blocks of smart applications that enhance our daily lives. Actors in this context refer to the entities capable of taking actions based on the data collected and processed by sensors. These can be machines, robots, algorithms, or even humans. WSANs represent the synergy between sensors and actors, forming a dynamic, self-organizing system that can respond to changing conditions, thereby offering greater intelligence and autonomy to IoT applications. This dynamic interaction between sensors and actors is the key to enabling smart, context-aware decision making and automation in various domains.

In this era of connectivity, the potential applications of smart systems in IoT and WSANs are boundless. From smart homes that adjust their environment based on your preferences to industrial setups that optimize processes and maintenance, and from precision agriculture that ensures sustainable food production to healthcare systems that monitor patients' health in real time, the IoT and WSANs are revolutionizing the way we live, work, and play.

This exploration of smart applications in the IoT and WSANs delves into the principles, technologies, and the wide array of domains where they are making a significant impact. As we journey through this dynamic landscape, we will uncover the ways in which these interconnected systems are shaping our future and propelling us into an era of unprecedented convenience, efficiency, and sustainability.

The topics covered include, but are not limited to, the following:

• Simulations and experiments;
• Energy management;
• Routing efficiency;
• Optimization algorithms;
• Applications;

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Sensor and Actuator Networks is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs).
