Energy optimization strategy on the IoT equipment based on the scheduler by Wanfang ZHAO, Yong HAN

“…A scheduling strategy to optimize energy consumption was proposed to reduce the energy consumption of the edge system in view of the fast growth of energy consumption demand in the internet of things.Based on the analysis of the power management architecture and the energy consumption composition in the typical multi-core terminal system,in view of the shortcomings of the existing system power management module,the scheduler load balancing mechanism was improved to control system energy consumption and the implementation process and implementation points of the strategy were given.The strategy was tested in the multi-core simulation system.The result shows that in low load scenarios,that is,in scenarios that CPU does not need to do data-intensive computing,the energy-saving effect of this strategy is obvious,such as data acquisition,equipment monitoring and other typical internet of things applications.…”

“…A channel model for frequency nonselective Rayleigh fading MIMO channel was set up and the channel model setting was extended to three-dimensional space.The mutual coupling between antenna elements was analyzed based on the equivalent network model of the multiple-antenna.The general spatial correlation expressions of channel model with the impact of mutual coupling were derived in the three-dimensional spatial channels.When the receivers were different antenna arrays,the effect of the angular parameters associated with the mean azimuth of arrival(MAOA),azimuth spread(AS),meant elevation of arrival(MEOA)and elevation spread(ES)on the MIMO system capacity was investigated.Numerical results verifiy the impact of different angle spread on spatial correlation with the mutual coupling and indicate that the system capacity is more dependent on the MAOA and MEOA than the AS and ES.…”
