The aim of this R&D work is to establish technology which will enable monitoring of large-scale distributed networks with accuracy. Compact sensors were distributed over a wide area network to perform research. With this technological development, several sensors were deployed at distributed locations, and they were managed and operated in both distributed and centralized manner. It was observed that several sensors were beneficial to identify the flow of fraudulent access.

A possible problem that may arise from increasing the number of sensors is the cost. However, it is feasible to use light and compact sensor groups. On defining management information for operation and implementing it, controlling sensors remotely becomes scalable. Systems set for the purpose of security often targeted for attack.

However with this sensor array security system sensors autonomously monitor each other, thus resulting in drastic reduction of operational costs and establishing technology that makes it possible to realize monitoring web that has no specific critical point.
