An outdoor air quality monitoring system based on ZigBee wireless sensor network is presented in this paper. A wireless network is formed by coordinators, routers, terminal notes, and especially PPB (part per billion) level high precision sensors. Data, sampled and processed by terminal notes, are sent to routers or the coordinator through a serial port, then displayed on a screen of a PC. The concentration...
Aiming at the problem that the existing GPRS monitoring system has no signal in some areas and the expensive price, an on-line monitoring system for transmission line based on 6LoWPAN technology is proposed. 6LoWPAN technology has built a bridge for communication between the wireless sensor and the Internet for the system, and achieved data collection, analysis to the transmission line temperature,...
In this paper, we present SAVI-MIB, a management information base (MIB) designed to support configuration and monitoring of SAVI protocol which can provide fine granularity source address validation. Objects are defined to meet the detailed management requirement of local networks and accommodate different scenarios. SAVI-MIB is implemented in switches and deployed in some campus networks. Objects...
This paper presents the design and implementation of a wireless monitoring system for building smart room architectures in home environments. The proposed system consists of wireless sensor nodes and actuator nodes which are organized into a monitoring network by ZigBee protocols. A base station and some general wireless nodes have been developed to form a prototype system. Various sensor and actuator...
In this paper, we focus on the problem of constructing an information gain model for stroke prevention in Ubiquitous Healthcare (U-Health) Wireless Body Area Networks (WBANs). We have constructed an information-based probabilistic relation model among the key indicators and sequenced their data gathering priority and precedence in the WBAN. Then, we constructed a cost function over the energy expenditure...
The information is an effective approach to raise the level of plant management in modern enterprises. Aimed at the problem that most of the enterprises face wire-monitoring, so starting with the work in plant running management and adopting the technology of WSN, and analyzes deeply the based on wireless sensor network in plant running management. By collecting plants states signal in WSN, get monitoring...
In this paper, oil and gas wells intelligent wireless monitoring system can real-time on-line and remotely monitor the information of flux, pressure and temperature in the oil pipelines fluid, can achieve the efficient management of data and sharing of resources, and can realize the enterprise managementpsilas automation and information. The users have shown that the system is running in good condition...
