Energy efficiency is one of the key requirements in Wireless Sensor Networks (WSNs). In order to optimize energy usage at sensor nodes, this paper proposes a new WSN architecture that relies on concepts of Software Defined Networking (SDN). Since SDN is a relatively new technology, originally envisioned for wired networks, it can't be expected to get immediately adopted in WSN domain, regardless of...
Emerging Wireless Sensor Networks (WSN) give support to a wide diversity of applications, but these networks are based on devices with limited resources, requiring communication protocols such as RPL (Routing Protocol for Low power lossy networks) which allow the routes to be fitted to certain requirements.

Lately the use of wireless sensor networks for monitoring seismic events has increased; however, these networks depends on the previous acknowledge of the infrastructure and topology. This topology can’t be updated if any of the nodes is lost during a seismic event, in addition the orientation of the first seismic wave can’t be predicted; because of this, it is necessary to use a type of dynamic network...
WSN is a wide area communication, because of its wide variety of applications. The main limitations in WSN are its limited battery or energy, BW, memory and wireless communication capability. In traditional approach each sensor node is used to sense the surrounding environment and communicate with the sink node hence the battery consumption and bandwidth utilization is more. To overcome these two...
The Deterministic Networking paradigm, which is prevalent in Operational Technology (OT), is now getting traction at the IETF and the IEEE, to enable the convergence of OT with Information Technology (IT), and the Industrial Internet vision, whereby the automation world can leverage IT technology to optimize OT processes.
