A recombination information process method of missing data in WSN

摘要

With reference to reducing dimensionality or predicting data missing mechanism, this paper approaches the function between distribution of missing data and topology of wireless sensor networks, and presents a recombination information missing data process method. As the missing data normally come from communication especially media accessing mechanism of carrier sense multiple access (CSMA) or time division multiple access (TDMA), the paper shows that the packets loss process is normally Poisson stochastic process. And the paper studies maximum missing data rates of some different topology networks (for example, the topology of star, hierarchical cluster tree, and mesh). In the end, the paper estimates the recombination information missing data processes method by simulations and experiments.
