Energy-Efficient and Delay-Minimizing Charging Method With a Multiple Directional Mobile Charger
IEEE Internet of Things Journal, 2021To prolong the battery lifetime of Internet-of-Things (IoT) devices, they can be charged by a mobile charger (MC) equipped with radio frequency (RF)-based wireless power transfer (WPT) capability. By concentrating power toward IoT devices, the energy efficiency of the MC increases when using a directional antenna instead of an omnidirectional ...

Efficient, distributed coordination of multiple mobile chargers in sensor networks
Proceedings of the 16th ACM international conference on Modeling, analysis & simulation of wireless and mobile systems, 2013We investigate the problem of efficient wireless energy recharging in Wireless Rechargeable Sensor Networks (WRSNs). In such networks special mobile entities (called the Mobile Chargers) traverse the network and wirelessly replenish the energy of sensor nodes.

IEEE Transactions on Sustainable Computing, 2021
Mobile charging can provide stable and reliable energy replenishment for wireless rechargeable sensor network (WRSN). However, relatively low charging utility exists in existing solutions. In this paper, we present a utility-based collaborative charging (UBCC) strategy to maximize the charging utility of mobile chargers (MCs) in large-scale WRSNs ...

Towards Perpetual Sensor Networks via Deploying Multiple Mobile Wireless Chargers
2014 43rd International Conference on Parallel Processing, 2014In this paper, we study the use of multiple mobile charging vehicles to charge sensors in a large-scale wireless sensor network for a given monitoring period, where sensors can be charged by the vehicles with wireless power transfer. Since each sensor may experience multiple charges to avoid its energy expiration for the period, we first consider a ...

Recharge Scheduling with Multiple Mobile Chargers
2016This chapter studies the important research scheduling problem for wireless charging in wireless sensor networks. We first present a distributed protocol that can collect energy information from the network on demand. For scalability, the protocol divides the network into hierarchical levels, selects head nodes on each level and establishes routing ...
