In which separation of the sensor nodes based on their location given by the node electronics using GPS, into certain regions are classified. Sink node (base station) is established away from the sensing region and a gateway node at the middle of sensing region. If the distance of sensor nodes from sink node and gateway node...
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...

Although Wireless Sensor Networks (WSNn) are designed to operate with low power consumption, much of the research in this field focuses on improving the efficiency of resource usage. In many scenarios, WSNs are configured to monitor and transmit the observed data periodically.
