Efficient Wireless Recharging in Sensor Networks

2013 IEEE International Conference on Distributed Computing in Sensor Systems, 2013
We study the problem of efficient wireless energy recharging in Wireless Rechargeable Sensor Networks (WRSN). In such networks a special mobile entity (called the Mobile Charger) traverses the network and wirelessly replenishes the energy of sensor nodes.

Sensor Mission Assignment in Rechargeable Wireless Sensor Networks

ACM Transactions on Sensor Networks, 2014
Sensor mission assignment involves matching the sensing resources of a wireless sensor network (WSN) to appropriate tasks (missions), which may come to the network dynamically. Although solutions for WSNs with battery-operated nodes have been proposed for this problem, no attention has been given to networks whose nodes have energy-harvesting ...

Energy Provisioning in Wireless Rechargeable Sensor Networks

IEEE Transactions on Mobile Computing, 2011
Wireless rechargeable sensor networks (WRSNs) have emerged as an alternative to solving the challenges of size and operation time posed by traditional battery-powered systems. In this paper, we study a WRSN built from the industrial wireless identification and sensing platform (WISP) and commercial off-the-shelf RFID readers.

Programming wireless recharging for target-oriented rechargeable sensor networks

Proceedings of the 11th IEEE International Conference on Networking, Sensing and Control, 2014
Wireless rechargeable sensors can receive energy from mobile chargers directly. For fulfilling differentiated application requirements, the charger should be programmed in advance to schedule its limited time budget on moving itself and charging individual sensors.

Broker-Based Nodes Recharging Scheme for Surveillance Wireless Rechargeable Sensor Networks

IEEE Sensors Journal, 2021
In Surveillance Wireless Sensor Networks (SWSN), the nodes are distributed at the borders to detect unauthorized intrusions. In such applications, as the nodes are usually equipped with limited batteries and the network area is harsh to be accessible for humans, energy efficiency is considered as one of the main issues in designing the sensor networks.

Wireless Charger Deployment Optimization for Wireless Rechargeable Sensor Networks

2014 7th International Conference on Ubi-Media Computing and Workshops, 2014
In a wireless rechargeable sensor network (WRSN), sensor nodes can harvest energy from wireless chargers to refill their power supplies so that the WRSN can operate sustainably. This paper considers wireless chargers equipped with 3D-beamforming directional antennas, and assumes they can be deployed on grid points at a fixed height to propose two ...

MSR: Minimum-Stop Recharging Scheme for Wireless Rechargeable Sensor Networks

2014 IEEE 11th Intl Conf on Ubiquitous Intelligence and Computing and 2014 IEEE 11th Intl Conf on Autonomic and Trusted Computing and 2014 IEEE 14th Intl Conf on Scalable Computing and Communications and Its Associated Workshops, 2014
This paper deals with simultaneous energy transfer to multiple nodes for scalable wireless recharging in wireless sensor networks. All existing recharging schemes rely on the use of a mobile charger that roves the network and drops by some locations for nodes recharging.
