The idea of smart home has been proposed for many years. However, the heterogeneity of device and data restricts the spread of it. Otherwise, the lack of underlying formal semantics between devices impedes the reusing and sharing classification across systems. We present a concept ontology in smart home which can capture the features of domain knowledge. A system architecture of smart home based on the concept ontology is constructed.

In this paper, we studied the trust management problem in one-hop cluster-based underwater wireless sensor networks (UWSNs). Trust plays an important role in constructing UWSNs. Due to the dynamic natures of UWSNs (current movement, addition or deletion of nodes) and the massive deployment of underwater sensor nodes, coupled with the short range of water acoustic communications, we need to ensure that all communicating nodes are trusted. We propose a hierarchical trust management scheme for one-hop cluster-based underwater wireless sensor networks.

This paper mainly studies the design and research of remote wireless sensor networks. This system features low power consumption, strong anti-interference ability, large capacity, real-time acquisition, and safe and reliable data transmission. The research idea of this paper: The host connects up to 255 extensions through the wireless transmission module, and the host sends standard MODBUS (RTU) access commands to control the operation of each extension.
