Recent Advances and Challenges in Wireless Multimedia Sensor Networks

Wireless Sensor Networks (WSNs) Akyildiz et al. (2002), Zhao & Guibas (2009) are formed of spatially distributed autonomous sensor nodes (motes). They are deployed in an environment where they can be used to monitor environmental conditions in collaboration, and communicate with each other through the wireless links. Several applications that are used in different areas have been outlined in th...

Current technological advances in sensors, power efficient integrated circuits, and wireless transferring have allowed the development of miniature, lightweight, low-cost, and smart physiological sensor nodes. These sensor nodes have capacity of sensing, controlling, processing, and communication one or more vital signs. Furthermore, they can be used in wireless personal area networks (WPANs) o...

Recent Advances of Secure Clustering Protocols in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) have been employed in many real-world applications that greatly improve our life. The ubiquitous WSNs make security a prime issue, and new technologies have been developed recently. In this article, we review the most recent secure clustering protocols in WSNs. We start with a description of the security requirements for WSNs and discuss the existing security sch...

Advances in Wireless Sensor Networks

INTRODUCTION The origins of networks of sensors can be traced back to the 1980s when DARPA initiated the Distributed Sensor Networks program. However, recent advances in microprocessor fabrication have led to a dramatic reduction in both the physical size and power consumption of such devices. Battery and sensing technology as well as communications hardware have also followed a similar miniatu...
