Quality-Driven Energy-Neutralized Power and Relay Selection for Smart Grid Wireless Multimedia Sensor Based IoTs

With the popularity of photovoltaic based green energy in smart grid systems, accurate information gathering becomes a critical issue in predicting microgrid power input. In this paper, we propose a new quality-optimized multimedia information gathering scheme, in the energy harvesting wireless sensor networks based Internet of things system, to provide the best-effort sky camera information accuracy for further predicting available photovoltaic power. In the proposed approach, the power control and relay node selection strategies are jointly optimized to achieve maximum sky camera image quality subject to the harvestable energy neutrality constraint. Simulation results show that the proposed scheme can improve multimedia data transmission quality by exploring adaptive transmission power and relay selection strategy.
