Near-field radio frequency identification (RFID) tags have a number of unique features such as being wirelessly powered, having ultra low power communication capabilities, small size, and low cost. These qualities paired with the increasing availability of commodity near field communication (NFC) enabled smart phones presents a significant opportunity to enable a wide range of new applications and...
In remote health care Body Area Networks (BAN) are very popular but demand low energy consumption due to very constrained resources. For it several protocols, such as ZigBee, BlueTooth, WiFi etc, have been proposed but non has delivered the optimum results. These systems also demand vast interoperability among devices. Recently a propriety protocol ANT+ provides such features and strengthens the goals...
With every bite you and I throw away, someone, somewhere in the world goes hungry. A report by the Institution of Mechanical Engineers on global food wastage states that 50 percent of all food produced around the world never reaches a human mouth. When a country like India is on its way to become a superpower and its reports say that this year's production leaves the government with 75 million ton...
Physical and environmental sensing is benefitting several domains to solve real time problems. Wireless Sensor and Actuator Networks (WSAN) are emerging as the new generation of sensor networks and providing a boost towards the development of autonomous systems. Use of WSAN towards crop irrigation is one of the top most utilization in the area of Agriculture. In this paper we have presented the crop...
In the last years the number of papers related to wireless sensor networks has increased substantially. Most of them focus in raising issues as routing algorithms, network lifetime, and more recently, Multiple Input Multiple Output wireless networks. In contrast with all those studies, we present a practical application of wireless networks: The sensing of the pH and temperature for a fish farm. The...

This paper discusses the application of the process monitoring and control for radon chamber with WinCC, configuration software with a human-machine interface (HMI) and supervisory control and data acquisition (SCADA), which is used to monitor the dynamical industrial process. Both software and hardware-based implementations of this system are described in detail, including the dynamic replenishment...
In recent years, Zigbee becomes one of the most promising protocols for wireless home networking. So, it will be essential for home gateways to interoperate with Zigbee home network devices. In this paper, I propose an OSGi-based architecture for dynamic integration of Zigbee home networks into home gateways, where the Zigbee home network devices are represented as device proxy service bundles. Such...
One of the major applications of wireless sensor networks is guiding navigation service whose goal is to find a way to guide moving objects across a hazardous region covered by sensors. Sensor networks maintain safe paths by which the moving objects can be guided safely to exits. In this paper, we propose a distributed guiding navigation protocol for constructing area-to-area optimal guiding paths...
In sensor network-related researches, communication has been the most important target for reducing energy consumption. The frequencies in communication and sensing in a sensor node affect its energy efficiency. Therefore, the sensing cycle and the transmission cycle in a sensor node need to be managed to increase energy efficiency in communication. In this paper we present mechanisms to manage sensor...
wildCENSE is a Wireless Sensor Network (WSN) system which attempts to monitor the behaviour and migration patterns of Barasingha (Swamp Deer). The system would collect the micro-climatic as well as positional information of the animal and communicate it to a base station through flooding of data using peer-to-peer network. The base station, using a gateway, will upload all the collected data to a...
Physical clustering in wireless sensor networks results in the nomination of 'cluster heads'. The cluster head acts as a hub for the cluster. It is a specific node which has superior energy capabilities when compared with the other members of the same cluster. The nomination of cluster head is performed periodically or iteratively. This process is termed as re-clustering. Reclustering is energy-consuming...
This paper introduces an intelligent sink mechanism based on the observation and analysis of non-uniform energy consumption problem in sensor network, in which more energy consumed at nodes near the sink than at nodes far away. The proposed intelligent sink utilizes dynamic sink proxies for localized data query and collection, so as to achieve highly distributed and low energy consumption among sensor...
We describe the successful development and deployment of an environmental sensor network deployed in the Great Crowden Brook catchment area of the Peak District, UK. The main aim was to assess our deployment methodology for "multi-hop" networks and assess the sensor node technology choices from an operational perspective, so as to inform ongoing development of a complete hydrological sensor...
Smart Homes uses different devices including sensors and actuators to provide services that assist in performing the activities of daily living. Currently these smart homes are developed in a manual and adhoc way. Manually configured smart homes create scalability, extensibility and cost problem. The need for a uniform platform for intercommunication among devices and a middleware abstraction using...
Recent advances in wireless sensor networks have led to many new protocols specifically designed for sensor networks where energy awareness is an essential consideration. Attention has been mostly directed towards routing protocols. These protocols generally implement a view embracing a local energy reserve. This paper presents an algorithm for determining optimal paths connecting sensor nodes to...
Ad-hoc sensor networks provide a cheap and scalable technology for constructing pervasive learning assessment systems that are embedded in physical environments. This paper proposes an extension to the QTI assessment standard that supports localized sensor data from sensor networks by incorporating the Sensor-ML notation. This extension can lead to a new class of pervasive learning environments where...
