SMEH: Stochastic Method of Energy Harvesting for Powering up Mobile Phones

Abstract

from surrounding sources [3]. At 915mhz, legislature regulations restrain the yield force of radios utilizing unlicensed recurrence groups to 4w successful isotropic radiated power, as on account of radio-frequency ID investigative specialists. The RF energy can be utilized for charging or operating in a wide range of low-powered devices. It is already known that ambient radio frequencies are universally existing over an maximized range of available frequencies as well as levels of energy. It is more available in urban area populated with users with more number of mobile devices. The RF waves emitted from such mobile devices uniquely represents a widely availability of the power if it can be efficiently used for harvesting the energy for charging the low-powered computing devices. With the growing number of population adopting smart phones and usage of 3G networks, there is a large availability of RF waves that can be exploiting for the purpose of energy harvesting. Dedicated power transmitters further enable engineered and predictable wireless power solutions. With continued decreases in the power consumption of electronic components, increased sensitivity of passive receivers for RF harvesting, and improved performance of low-leakage energy storage devices, the applications for wire-free charging by means of RF-based wireless power and energy harvesting will continue to grow. This paper presents a mathematical model that adopts stochastic and probability theory to perform optimization of the RF energy for powering up mobile devices. Section II discusses about some of the recent studied performed in the area of energy harvesting followed by Section III that discusses about the problem identification of the proposed study. Proposed model is briefly introduced in Section IV, while Section V discusses about the adopted design principles. The implementation part of the proposed system is discussed in Section VI, while the result discussion with respect to the comparative performance analysis is discussed in Section VII. Finally, Section VIII makes some concluding statement of the proposed study and summarizes the outcome of the study.
