This paper aims at providing a green battery solution for practical wireless communication systems. First, we discuss the demands and latest developments of wireless energy transfer (WET) in relevant industries. Second, we propose a user- centric energy-efficient approach in wireless powered communication networks (WPCNs), where mobile users first harvest energy from a dedicated power station and...
This paper describes new algorithms for throughput optimization in a mobile backbone network. This hierarchical communication framework combines mobile backbone nodes, which have superior mobility and communication capability, with regular nodes, which are constrained in mobility and communication capability. An important quantity of interest in mobile backbone networks is the number of regular nodes...
Recent work shows that sink mobility along a constrained path can improve the energy efficiency in wireless sensor networks. However, due to the path constraint, a mobile sink with constant speed has limited communication time to collect data from the sensor nodes deployed randomly. This poses significant challenges in simultaneously improving the amount of data collected and prolonging network lifetime...
