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 ...

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 ...

An Adaptive MAC Protocol for Wireless Rechargeable Sensor Networks

2017
In the existing medium access control (MAC) protocols of rechargeable sensor networks, the maximum charging threshold of sensor nodes generally set to a fixed value based on nodes battery capacity. It leads to the channel occupied due to the long time charging of node so that the data cannot be transmitted on time.

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 ...

A Wireless Sensor Network Recharging Strategy by Balancing Lifespan of Sensor Nodes

2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017
The life of many wireless sensor networks is limited by their battery-based energy source. Recharging batteries from a distance by the wireless energy transferring technique could lift this restriction. However, how to deploy the mobile charging device requires further research.
