sensors

In Recent years we have witnessed tremendous advances in wirelessly networked and embedded sensors. Wireless sensor nodes are typically low-cost, low-power, small devices equipped with limited sensing, data processing and wireless communication capabilities, as well as power supply. With the continuation of Moore’s law, they are becoming smaller, cheaper, while more powerful and more pervasive. The proliferation of these products opens up unprecedented opportunities for a wide variety of scientific, industrial, agricultural, commercial and military applications, such as health care, smart transportation, emergency response, home automation, social studies, critical infrastructure protection, and target tracking, just to mention a few. In particular, wireless sensors are a key enabling technology for the emerging cyber-physical systems, which will ultimately improve the quality of life. To realize the full potential of wireless sensors, enormous challenges need to be addressed and  efforts have been made in this field.

This special issue aims to gather latest research and development achievements in wireless sensors and to promote their applications in real world. Original and unpublished papers that address the most current issues and challenges are solicited in all aspects of wireless sensors, including, but not limited to, theoretical studies, methods, technologies, prototypes, and practical applications.
