Energy Harvesting (EH) nodes, which harvest energy from the environment in order to communicate over a wireless link, promise perpetual operation of a wireless network with battery-powered nodes. In this paper, we address the throughput optimization problem for a rate-adaptive EH node that chooses its rate from a set of discrete rates and adjusts its power depending on its channel gain and battery...
In wireless networks environment, nodes are powered by exhaustible energy provided by batteries with limited duration. When the energy budget of a node comes to exhaustion, many undesirable situations may occur, ranking from minor alternative route discovery to unbearable network partition. Another situation which has not yet paid attention is one reached when a distributed application requires more...
A node in a wireless sensor network typically consists of a micro-controller, a communication device or transceiver, and a battery unit for powering the transceiver and other devices. An important feature of wireless sensor networks is the low power consumption requirement, since these sensor nodes carry generally irreplaceable power sources or batteries. We consider the problem of assigning a power...
