Energy Neutral Operation (ENO) has created the ability to continuously operate wireless sensor networks in areas such as environmental monitoring, hazard detection and industrial IoT applications. Current ENO approaches utilise techniques such as sample rate control, adaptive duty cycling and data reduction methods to balance energy generation, storage and consumption. However, the state of the art...
A Wireless Sensor Network (WSN) is a network of thousands of low-cost sensors which have a limited operating lifetime. A sensor node generally comprises four basic elements, including a transceiver unit, a detection unit, a processing unit, and an energy supply unit. One of the major challenges in the WSN is to increase the network life-time. Since the transmitting/receiving unit has the highest energy...

Generally the data sensed by the sensors are collected and routed to the sink in a specific manner for further processing. In this proposed work, the sink node is dynamic rather than being mobile. The dynamic sink collects the data from the pervasive environment continuously. The dynamic route (path) to the sink is established, maintained and updated. Finally the comparison is made between the mobile...
WSNs are composed of sensors that collect, process, and send data to a sink. To communicate, sensors use a shared medium. Thus, a robust MAC layer protocol has to be implemented for transmission management. This paper presents a QoS based WSNs MAC protocol that ensures service differentiation and less energy consumption. It is based on a duty-cycle approach that combines TDMA and CSMA/CA schemes....
In this paper we consider the problem of hosting multiple applications in software-defined wireless sensor networks (SD-WSNs).

In wireless sensor networks (WSNs), energy is dissipated mainly when sensors are communicating with sinks. As a result, multiple sinks are deployed in the network in order to increase its coverage area and shorten the communication distance between these two entities. This raises the issue of how best to bind sensors to sinks without overloading any sink. In this paper, we solve the sensor-to-sink...
Wireless sensor networks consist of small battery powered devices with limited energy resources. The small sensor nodes are usually inaccessible to the users due to their remote deployment.
