Sensor network based on mutual communications with reliability index

In the environment such as outer space where we cannot maintain the artifacts, it is the robustness that is important for artifacts. Thus the system which has the information processing circuit realizing self-maintenance function is desirable. So far some approach is tried to realize self-maintenance function using the qualitative reasoning technique. In this study, we try to apply distributed information processing technique to this qualitative reasoning information processor, by arranging many operating homogeneous units onto an application specific integrated circuit (ASIC). Now we are investigating the way mounting the self-maintenance logic on large scale artifact.
