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,...
The description of the existing wireless data communication solutions by 6LoWPAN standard, and the organization of sensor networks are presented. The use of freeware embedded operating systems is discussed. The organization a network using the SimpliciTI is demonstrated.
Nodes in low-rate wireless sensor networks (LR-WSN) are often placed in the bad environment intensively, and node energy consumption makes the network topology structure change dynamically, resulting in coverage of the case in which the actual testing process can not meet the requirements. In order to facilitate users' remote testing, this paper builds a conformance test platform of LR-WSN, proposes...
Telecommunications are evolving fast, with many trends being observed at the several layers of the system/network structure. “Networks of the Future” and “Future Internet” became trends that encompass many views and goals, namely within mobile and wireless communications, most of them related to network aspects, as well as services and applications. This paper reviews the trends mentioned above, and...
This design combines sensor network, embedded system, Internet information service and database to provide patients a safe, easy and integral wireless healthcare system. Safety is ensured by the advantage of applications based on Windows Mobile. Moreover, the GUI made it possible for elder patients to use the software easily, while Internet Health Service makes the healthcare be more integral.
The following topics are dealt with: optical Internet; nanophotonics; green ICT; solar cells; LED; wireless mesh and sensor network; and optical switching and routing.
This paper presents the methodology how to utilize sensor networks in order to predict human's thermal comfort and sensation. The neural network was dynamically organized on the basis of correlations with the thermal sensation of the occupants and many other values in the sensor network, and the structure of the neural network was updated cyclically. In this paper, the air-conditioning system in an...
In upcoming ubiquitous environment, many real-time sensing applications will emerge. These applications show different scale and characteristics on delivery demands. The applications commonly depend on real-time understanding on data from widely distributed data sources. Also, they have highly diverse and complex delivery demands in terms of data and delay, e.g., data value ranges of interest, spatial...
This work presents a proposal for an Ambient Assisted Wheelchair (A2W). Such a vehicle could collect useful information provided by Intelligent Environments equipped with appropriate wireless services. Two different networks have been considered for this tasks: a standard Wi-Fi network that will allow a connection to Internet Services providing building accessibility information; and a specific sensor...
A case study of security risk analysis of a wireless body area network for remote health monitoring as a after measure for deploying security and privacy features is introduced in this paper. The target system has a scalable platform that requires minimum human interaction during setup and monitoring. The core components of the system include: (i) biosensor/transceiver pairs, (ii) hardware modules...
A way of evaluation of a topology structure model, especially the Internet topology structure model, was studied. SLS (Signless Laplacian Spectra), is used to quantitatively identify the topology properties of the Internet generated by the model and the Internet out of real measuring. SLS eigenvectors could be gained out of this procedure, then a cross-correlation algorithm was performed on the eigenvectors...
The base technologies for realizing distributed sensor network systems using many wireless sensor terminals have developed rapidly. The sensor network systems are expected to find applications in various fields such as disaster prevention, environmental monitoring, agricultural support, health care, logistics, and business applications. M2M (machine-to-machine) technology enables machines to communicate...
The maximum benefit out of the recent developments in sensor networking can be achieved via the integration of sensors with Internet. The real-time specific sensor data must be processed and the action must be taken instantaneously. The integration controller module of the proposed architecture integrates the sensor network and Internet using Cloud Technology which offers the benefit of reliability,...
We deployed Field Servers in tropical zones such as India and Thailand for challenges in high temperature and found several problems to be solved technologically. Deployment of Field Servers under high temperature and lack of broad band Internet service is still big challenge as we so far deployed in Himalaya. High temperature and strong solar radiation destroyed low-cost Field Servers in half years...
Sensor networks consist of various sensors. Existing development of sensor networks is hard to federation and communication each other because they use different data format depend on their characteristics. Thereby, it needs to middleware that can merge raw data from heterogeneous sensor networks. For that reason, we propose sensor network middleware that able to translate sensed data from sensor...
In order to counter the barriers of care for mobility-impaired person, like ageing citizens and terminal cancer patient, we plan a platform, u-care system that integrates wireless telecommunication, sensor network, and information technology to take care of the mobility impaired person, elderly and terminal cancer patient. Through the u-care system, the digital art contents were streaming through...
Recently, environment monitoring system attracts attention because global and/or local disasters such as global warming problem, air pollution, heavy rain and flood etc. occur everywhere. In addition, some people and companies have a weather sensor and broad band internet service become widespread as weather sensor and internet service cost lower. Many of these existing sensor network are operated...
The NIST-supported IEEE 1451 set of standards is being developed to unify diverse standards by providing a base protocol which allows interoperability between sensor/actuator networks and busses. A key feature of the IEEE 1451 standard is that the data (and meta-data or TEDS) of all transducers are communicated on the Internet with the same format, independent of the sensor physical layer (wired or...
