Researchers from Gwangju Institute of Science and Technology (GIST) Report on Findings in General Mathematics

  2012 AUG 8 (VerticalNews) -- By a News Reporter-Staff News Editor at Telecommunications Weekly -- Fresh data on General Mathematics are presented in a new report. According to news originating from Kwangju, South Korea, by VerticalNews correspondents, research stated, "We address a state estimation problem over a large-scale sensor network with uncertain communication channel. Consensus protocol is usually used to adapt a large-scale sensor network."

  Our news journalists obtained a quote from the research from the Gwangju Institute of Science and Technology (GIST), "However, when certain parts of communication channels are broken down, the accuracy performance is seriously degraded. Specifically, outliers in the channel or temporal disconnection are avoided via proposed method for the practical implementation of the distributed estimation over large-scale sensor networks. We handle this practical challenge by using adaptive channel status estimator and robust L1-norm Kalman filter in design of the processor of the individual sensor node. Then, they are incorporated into the consensus algorithm in order to achieve the robust distributed state estimation."

  According to the news editors, the researchers concluded: "The robust property of the proposed algorithm enables the sensor network to selectively weight sensors of normal conditions so that the filter can be practically useful."
