Aiming at monitoring information of HCHO, CH4, LPG and other toxic and harmful gas concentrations in the chemical production plant, the monitoring system designed a ZigBee wireless sensor network composed of CC2430, MC114 and MS1100 gas sensor, which built a safe, low power consumption, flexible detection system of toxic and harmful gas concentrations. As the system data transmission with the mode...
Wireless home networks are extending beyond phones and computers to include every imaginable type of electronic device from TVs and audio components, to appliances and thermostats. The benefits include distribution of multimedia throughout the home, energy savings through remote or automatic control, and reduced cost through packaged services. Though people are often enamored by the technology that...
This paper aims at presenting a method to lower the power consumption of the wireless home sensory and controlling systems. To realize it, we put forward a new network layer called ??Pithur??, which is based on IEEE 802.15.4 and can extend the battery life to 7~9 times than that of a Zigbee network, at the cost of lower performance and longer latency time. Also we lowered the power consumption of...
For participants of diabetes prevention programs, we consider that it is effective to record vital signs, such as weight and blood pressure, and to receive instruction based on such readings during the follow-up period in order to avoid rebound. Although the Internet is an effective medium for recording data and reporting everyday health status, health support systems that require the use of a PC...
This extended abstract describes a poster and a proposal for demonstration. Its focus is on low rate wireless personal area networks (LR-WPANs) which use IEEE 802.15.4 physical and MAC layers at the lower layers of the protocol stack. More precisely, goal of this extended abstract is to present a real test-bed, whose main goal is to demonstrate how IEEE 802.15.4 LR-WPANs can fully inter-operate with...
This paper investigates an architecture for interconnecting Internet and Zigbee sensor network which is founded on IEEE802.15.4 standard. We present a Web-sensor gateway to deliver data between Internet protocol and Zigbee/IEEE802.15.4 protocol, transparently. We also introduce the common gateway interface (CGI) technology to satisfy users on the Web browser to efficiently manage and query the Zigbee...
In recent years, the home environment has seen a rapid introduction of network enabled digital technology. This technology offers new and exciting opportunities to increase the connectivity of devices within the home for the purpose of home automation. Moreover, with the rapid expansion of the Internet, there is the added potential for the remote control and monitoring of such network enabled devices...
SmartBee is a vertical solution given to control/monitor smart home/office devices, interconnecting IP and ZigBee networks. The key product of the system is SmartBee Gateway. In one end, it is connected with SmartBee enabled End Devices through ZigBee network. On the other end, it connects to internet so that the devices are accessible via multiple channels using IP. SmartBee Specification is introduced...
WSN using ZigBee is gaining an exponentially increasing interest from industry and is considered as a universal solution for emerging application including home automation, health care, surveillance, and so on. To provide automation and remote control application service, WSN is inter-working with high speed Internet through Gateway-Sink node. In this paper, we first introduce service network, then...
