Recharging path construction for mobile recharger in wireless sensor networks

2016 IEEE International Conference on Consumer Electronics-Taiwan (ICCE-TW), 2016
Wireless recharging becomes one of the most important problems in wireless sensor networks recently. This paper aims to construct a recharging path for mobile anchor to efficiently recharge the battery of each sensor in a given WSN. Initially, the boundary of recharging circle is analyzed such that mobile anchor can fully recharge the battery of any ...

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 ...

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.

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.

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 ...
