Internet of Things (IoT) has revolutionized the traditional Internet where only human-centric services were offered. It has enabled objects to have the ability to connect and communicate through the Internet. IoT has several applications such as smart water management systems. However, they require high energy-efficient sensor nodes that are able to communicate across long distance. This motivates...
Social Networking Sites (SNS) require a centralized system accessible via Internet. SNS' owners are in control of user's data; this often leads to data theft, piracy and privacy issues. This paper proposes a way of socializing with people in surrounding places by using a ubiquitous social sensor network system (USSNS) where Wireless Sensor Node interact in a peer-to-peer mode without the need of Internet...
The main node (router, coordinator, gateway) of ZigBee based wireless sensor network enhanced by adoption of Bluetooth module is proposed in this paper to provide easy way for industrial field measurement with low-cost and portability. Only a Bluetooth module and basic circuits are required to be added to the original ZigBee network and a simplified physical model is designed and verified in wireless...
Wireless Sensor Network (WSN) usage for buildings and household has been increasingly popular because it offers various benefits, such as home automation and home surveillance. Therefore, in order to increase WSN usage flexibility, remote controlling which enables remote administration is required. In fact, generally WSN is controlled by a coordinator (sink node) that is located closely to the WSN...
With radio frequency technology and wireless broadband technology and the development of sensor technology, the advent of the era of Internet of things, from the traditional video monitoring system has been monitoring to monitoring based on wireless sensor network (WSN), different functions of sensor outside all kinds of information collection, information system can to sensory information, process...
We propose a new method of multichannel allocation and routing for wireless mesh networks where each node generates event-driven video sensor data. Battery powered video camera sensors are often connected wirelessly to cover a large area. Such wireless video sensor networks are considered as major applications of Internet of Things (IoT). We analyze the power consumption model for wireless video sensor...
VoIP refers to communications services —voice and/or voice-messaging applications— that are transported via the Internet, rather than the public switched telephone network (PSTN). Rate of evolution of mobile services (such as data transfer service (GPRS, EDGE, 3G, and 4G LTE), audio & video player service, camera with higher resolution, GPS) is much higher than that of energy resources or energy...
To overcome resource conflict occurred in data broadcasting among nodes which are shared and interferential each other on radio channels in sensor network, in the article we propose fuzzy Hopfield neural network(FHNN) in order to solve TDMA broadcast scheduling problem of wireless sensor network. We considered it as discrete energy minimization problem and mapped it into Hopfield neural network with...
Wireless sensor network is very useful technology for real-time slope health monitoring under remote and hostile environments. We design a 3-level of wireless sensor network hierarchy which consists of data collection layer, data transmission layer and remote safety monitoring center. Data collection layer includes information collection nodes, route nodes and coordinate nodes. Data collection layer...
The Internet of Things (IoT) is the paradigm of inter connecting heterogeneous devices which are distributed globally and will be a part of the future Internet. Wireless Sensor Networks (WSN) are one of the integral classes of networks in the IoT. One of the major challenges to achieve IoT is to integrate and manage large heterogeneous networks. Autonomic network management system is the need of the...
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)...
Ubiquitous technology through sensor networks is being applied to numerous industrial fields specially to increase the quality of human life (QoL). Therefore, Wireless Sensor Networks (WSNs) lossless data is one of the communications challenges to provide accurate data. Although, end-to-end data retransmission has evolved as a reliable transportation in Internet, this method is not applicable to WSNs...
Cyber-Physical Systems require the integration of various heterogeneous networks. To evaluate proposed algorithms in network research, real-world test beds are an indispensable complement to simulations.

People and objects in the special area can be perceived, identified and localized by RFIDs, and they can also get the information they need. The model has been applied...
As the development of sensor technology and communication technology, the realization of smart home is not longer out of reach. This paper provides a design of smart home system based on wireless sensor network (WSN) within the ZigBee criterion. For the different network condition of different houses, we employ different networks (Internet or UMTS) to achieve remote control of the house's electric...
In order to become truly ubiquitous, the Internet of Things (IoT) has to evolve to provide connectivity anytime, any place, for any thing. IEEE 802.15.4-based wireless personal area networks (WPANs) is a preferable communication method for IoT. Wireless personal area networks (WPANs) are used to convey information over relatively short distances. Connections effected via WPANs involve little or no...
The significance of forest fire monitoring was determined by the importance of forest resource and the destructive of forest fire. In the paper, according to the limitation of traditional forest fire monitoring schemes, a new wireless network implementation scheme oriented to forest fire monitoring was presented based on GPRS communication technology and ZigBee technology. The related hardware schemes...
Clustering is an effective approach to hierarchically organizing network topology and to prolong the lifetime of a wireless sensor network. Current clustering protocols usually utilize two techniques: selecting cluster heads with more residual energy and rotating cluster heads periodically to distribute the energy consumption among nodes in each cluster. Most of the researches in this field has focused...
