Abstract (in Japanese) (See Japanese page) 
(in English) Wireless sensor network, which consists of a number of sensor nodes with signal processing and
communication capabilities, has been drawing a lot of research interest.
In recent years, R. Ghrist et al. have developed algebraic topological methods for the
analysis of sensor networks.
At first in this article, their pioneering works on homology groups and covering problems are
explained in detail.
Then, our approach in order to apply Ghrist's ideas to practical scenarios is presented.
Keyword (in Japanese) (See Japanese page) 
(in English) sensor network / covering problem / homology group / Mayer-Vietoris sequence / / / /
