Power control is the mechanism used in industries, large organization as well as in small sectors like home automation for the reduction of transmitting output powering the communication system to achieve good performance of the system. The power management is a technical mechanism which is used in the network devices to prevent the interference between different wireless networks and reduce the used...
The Internet of Things (IoT) vision is a hot research topic which enables all kinds of devices to connect together and share information seamlessly. IEEE 802.15.4 Low power Wireless Personal Area Networks (LoWPAN) and IPv6 over LoWPAN (IETF 6LoWPAN) defines standards and protocols for resource constrained Wireless Sensor Networks (WSN). Constrained Application Protocol (CoAP) is an emerging application...
Due to the remote environment of WSN, it is of great necessity for users to control and access remotely, which also needs support from WAN (such as Internet).Various applications show the usefulness of a sensor network increases when the wireless sensor network (WSN) is connected to an IP-based network and medical monitoring is a typical application. We focused on address allocation and proposed a...
It is expected that in the near future smart objects will have an Internet connection -- this is the Internet of Things vision. Most of these objects compatible with the IEEE 802.15.4 standard are characterized by small size, power constrains, and small computing resources. Connecting such devices to the Internet is considered simultaneously the biggest challenge and a great opportunity for the Internet...
With the rapidly gaining ground of the Internet of things, wireless sensor networks (WSNs) will be bound to permeate more and more applications. However, due to the nature of these applications such as harsh environment, resource-limited wireless sensor networks are usually fault prone. Therefore, it is essential to provide effective fault management techniques and robust fault management frameworks...
This paper presents the design and implementation of an Embedded Laboratory Security Monitoring System (ELSMS). The system includes a web server which acquires video information through camera, and Wireless Sensor Network (WSN) which gets environmental parameters through sensors and sends them to the web server. Users can access the Monitoring Server (MS) through PCs or Wireless Mobile Terminals(WMT)...
Visualization tools make it easier for users to observe the status of the wireless sensor networks (WSNs). So far, developers of WSNs have created various visualization tools under certain project/research backgrounds. These tools, however, are limited in certain application scenarios, since the underlying packet formats are hard coded into the programs. For this purpose, we present NetViewer, a universal...
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...
System resources for WSN need to be efficiently managed & configured. In this paper, we provide an effectual architecture for resource management, provision and configuration for sensor network in the Future Internet schema. Resource management architecture, its modules and mechanism are discussed in this paper and the configuration management is provided as a case study.
With the application of SensorGIS technique in the monitor system of toxic gases. we can dynamic monitor the monitor scope as well as release and share the monitoring news realtime. The toxic and harmful gas monitor system based on this technique monitors the toxic and harmful gas in monitor scope timely using WSN. WebGIS can position analyze and synchronous dispay the news which has been monitored...
Wireless sensor networks (WSN) are getting increasingly attractive as a means to bridge between the physical and the virtual world. The current trends in communication see vast advances in wireless connectivity, leading to dynamic and complicated systems on top of which applications must be built. The task of designing these applications with such systems thus becomes much more complex. One common...
SunShine, integration of distributed wireless sensor network (WSNs) and internet, can reduce the cost of health monitoring and extend the sensing coverage. However, the management of SunShine with distributed WSNs is a complex task. In this paper, Service-Oriented Architecture (SOA) is applied to build the web-based management system for SunShine due to its flexibility and reusability. The architecture...
In the traditional laboratory surveillance system, its effectiveness depends on the number of cameras installed, but the price is too high, and most adopt fixed video, and often some dead ends, such as an emergency can not be real-time monitor. The purpose of this study propose a set of the use of a small number of network cameras and wireless sensors developed by combining real-time laboratory safety...
This article presents a solution for distant monitoring and control of the greenhouse system via internet. It has a web based user interface with possibility of managing the sensors and actuators. Also allows to log events on the system like humidity, temperature, light etc. This Web based distant monitoring system uses a high end PIC microcontroller based developer board with Ethernet adapter that...
This article puts forward a method to access the data and analyzed results from the monitoring system of environment based on WSN with the B/S mode. It resolves the problem of low speed of page refresh with Ajax. The experiment shows that the partial refresh feature of Ajax can make it possible for the users to get access to the data and analyzed results easily through the browser, and experience...
Wireless sensor networks present a great potential in monitoring systems. A vast scope of applications can take advantage of WSNs and, mainly because of their own nature, the aggregation of WSN nodes into groups provides more potential solutions when compared with traditional monitoring systems. This paper introduces the issue of multicast messages and their impact on battery resources of WSNs. It...
