This study aims to construct novel computing and networking technologies of wireless sensor networks toward low-cost and high-density earthquake monitoring systems, which we believe will be a killer application of wireless sensor networks. For the purpose, we worked on developing a compact hard real-time operating system, a multi-core CPU for wireless sensor nodes, and a network fundamental technology. Through actual deployment and management of the earthquake monitoring system, we confirmed the applicability of our developed technologies for applications which need high reliability.
