Joint Wireless Charging and Sensor Activity Management in Wireless Rechargeable Sensor Networks

2015 44th International Conference on Parallel Processing, 2015
Recent studies show that the novel wireless charging technology can extend the lifetime of Wireless Sensor Networks (WSNs) towards perpetual operations. Recharging Vehicles (RVs) can be applied in WSNs to recharge sensors conveniently via wireless charging devices.

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.

Spatiotemporal charging scheduling in wireless rechargeable sensor networks

Computer Communications, 2020
Abstract Wireless sensor networks have a wide range of applications. However, the battery-constrained energy limits the scope of network applications and timeliness. In this paper, we study how to schedule charging and allocate charging time simultaneously for a wireless sensor network for the purpose of prolonging network lifetime and improve ...

Recharge Interval and Packet Delay in Wireless Sensor Network with RF Recharging

2016 IEEE Global Communications Conference (GLOBECOM), 2016
Radio frequency (RF) recharging can extend maintenance-free operation of wireless sensor networks. However, the period between recharging is limited by the distance between the most distant sensor node and the master which sends out recharging pulses. To increase this period, we propose a scheme in which nodes are logically grouped into circular zones ...

Efficient energy management in wireless rechargeable sensor networks

Proceedings of the 15th ACM international conference on Modeling, analysis and simulation of wireless and mobile systems, 2012
Through recent technology advances in the field of wireless energy transmission, Wireless Rechargeable Sensor Networks (WRSN) have emerged. In this new paradigm for WSNs a mobile entity called Mobile Charger (MC) traverses the network and replenishes the dissipated energy of sensors.

Charging path optimization for wireless rechargeable sensor network

Peer-to-Peer Networking and Applications, 2020
In wireless rechargeable sensor networks(WRSNs), charging path planning becomes more and more important. In this paper, a charging path planning model based on high-dimensional multi-objective optimization is proposed, which takes life cycle, distance, energy consumption and charging time into consideration.

Adaptive, limited knowledge wireless recharging in sensor networks

Proceedings of the 11th ACM international symposium on Mobility management and wireless access, 2013
We investigate the problem of efficient wireless energy recharging in Wireless Rechargeable Sensor Networks (WRSNs). In such networks a special mobile entity (called the Mobile Charger) traverses the network and wirelessly replenishes the energy of sensor nodes.

Partial Charging Scheduling in Wireless Rechargeable Sensor Networks

2018 IEEE Global Communications Conference (GLOBECOM), 2018
Partial charging in wireless rechargeable sensor networks (WRSNs) has been proposed recently, offering an new alternative in dealing with non-schedulable charging tasks. Most previous charging scheduling algorithms assume that a mobile charger must replenish a sensor to its full energy capacity in fulfilling every charging task (non-preemptive tasks ...

Nodes Deployment for Coverage in Rechargeable Wireless Sensor Networks

IEEE Transactions on Vehicular Technology, 2019
This paper considers a novel problem in rechargeable wireless sensor networks (WSNs), given a set of locations with one or more targets, determine the minimum number of sensor nodes to deploy in order to ensure a given coverage quality. This problem is significant as sensor nodes are often used to monitor one or more valuable assets or critical ...
