In this study, we introduce the urban recharging infrastructure design problem with stochastic demands and capacitated recharging stations. Stochastic recharge demands shaped by daily transportation/logistics activity cycles, capacity limitations of recharging stations and users’ route preferences need to be considered simultaneously to address this urgent problem that focus on the inner city t...

This paper describes a method for automatically recharging the batteries on a mobile robot. The robot used in this project is the Nomadic .TechnologiesTM Nomad XR4000 mobile robot. The battery recharging system was implemented using the robot's built-in sensors to control docking with a simple recharging station. The recharging station has an AC power plug, an infra-red beacon and a target desi...

Recharging through radio frequency (RF) pulses is a promising approach to enhance the lifetime of wireless sensor networks (WSNs). In this paper, we propose a polling-based MAC protocol with round robin scheduling under Elimited service policy. In this model, the WSN coordinator sends a recharging pulse upon reception of a recharging request from one of the nodes. As both recharging and data co...

A method of recharging implantable biosensors based on solar radiation is proposed. Firstly, the models of the proposed method are developed. Secondly, the recharging processes based on solar radiation are simulated using Monte Carlo (MC) method and the energy distributions of sunlight within the different layers of human skin have been achieved and discussed. Finally, the simulation results ar...
