A primary purpose of sensing in a sensor network is to collect and aggregate information about a phenomenon of interest. The batteries on today's wireless sensor barely last a few days, and nodes typically expend a lot of energy in computation and wireless communication. Hence, the energy efficiency of the system is a major issue. Different representative mechanisms has been proposed to achieve a...
The satellite navigation system needs the forecast of the ionosphere. It's indispensable to select an efficient ionospheric model and predict the value of TEC. In this paper, the Klobuchar14 parameter model is introduced and the time series of the 14 parameters for ten years are generated by fitting the TEC in China region with the model. Then, with the two-variable regression analysis, the relationship...
