The area of energy harvesting has seen various evolutions among the research community. Although various studies have been attempted to address the issues of energy harvesting in the past decade, but very few studies are focused on using RF energy from mobile phones explicitly. Hence, the prime motive of the proposed study is to showcase a mathematical model of RF energy harvesting using stochastic approach termed as SMEH i.e. Stochastic Method of Energy Harvesting. SMEH is designed analytically and evaluated using simulation based approach considering various near real time constraints of mobile devices, traffic scenario, as well as discrete state definition of the system for better analytical evaluation. The outcome of the proposed system is analyzed using probability for loss of event, queuing delay, throughput and compared with the most recent standard work in the similar direction.

Abstract. This paper presents optimal shape design of planar array antennas for microwave energy harvesters. The topology optimization of the C4-symmetric array antenna is conducted to maximize their isotropic gain and minimize the return losses in a frequency band ranging from 1.5 to 3.5 GHz. Then, we design the rectifier by varying the circuit parameter based on measurement results to realize the impedance matching between the optimized antenna and rectifier. It is shown by experiment that the harvester composed of the optimized array antenna and rectifier has higher receiving voltage in comparison with the single one. Moreover, the resultant harvester is found to start operating when the arrival electric field is greater than 0.1 V/m.

In this paper, we introduce a testbed for testing the RF energy transfer technology in the Internet of Things (IoT) environment, and provide experimental results obtained by using the testbed. The IoT environment considered in this paper consists of a power beacon, which is able to wirelessly transfers energy via microwave, and multiple sensor nodes, which makes use of the energy received from the power beacon. We have implemented the testbed to experiment the RF energy transfer in such IoT environment. We have used off-the-shelf hardware components to build the testbed and have made the tesbed controlled by software so that various energy and data transmission protocol experiments can easily be conducted. We also provide experimental results and discuss the future research direction.
