Missing Value Estimation in Wireless Sensor Networks
FU Hui-juana · Jisuanji gongcheng · 2011
Missing value of sensory data often occurs in Wireless Sensor Networks(WSN).This paper proposes a distributed algorithm named SC,which consists of two approaches named SRS and CNI.The algorithm SC chooses CNI or SRS dynamically according to the number of child node of current node.The theory analysis shows that SC does not increase extra energy.Simulation results show that SC can get perfect accuracy and adaptability in different topology.
