Caching has shown the success in performance improvement for many wireless communications and networking systems. In this paper, we introduce a caching mechanism for the energy harvesting based Internet of Things (IoT) sensing service. In the service, a sensor harvests energy from an environment. The energy is stored in the battery, and the sensor uses it for sensing and transmitting the reading to...
Wireless energy harvesting is a promising feature for supplying energy to a wireless device. However, this wireless energy supply to a mobile node is random due to mobility. In this paper, we consider performance analysis and optimization for a mobile node with delay-limited communications and wireless energy harvesting capability. Three major issues are considered: 1) an optimal transmission policy...
