The paper deals with the problem of designing and implementing an inexpensive wide area sensors network for environmental radiological monitoring. To this aim, the measurement node takes advantage from a low-cost, Linux based, development platform, and some new open-source software tool, which are pushed towards a network-oriented vision of Internet of Things (IoT).
This paper presents a server-centric system used to gather and analyze the data coming from sensor nodes. We propose a general, easy-to-extend architecture that can be used in a seamless manner on any types of data, helping to mitigate failure and detect abnormal behavior. In order to decrease risks, the server side will analyze the data, modify trust values for each node and notify an administrator...
In recent years, an increasing number of researchers have become involved in wireless sensor networks (WSNs) and cloud computing. However, integrating WSN and cloud computing technology to monitor the environment is still an open issue. In this paper, we propose a mobile-device-based environmental monitor based on SaaS (Software as a Service) of cloud computing architecture. The proposed model is...

The paper presents a prototype mixed-mode wireless indoor positioning and navigation system. The main goal of the system is to provide accurate and reliable location information for visually impaired users. The system also enables access to location related context information. The radio nodes of the network can operate in two power modes providing basis for both rough and precise user positioning...
This paper presents a novel method for classification of multi-lead electrocardiogram (ECG) signals. The feature extraction is based on the random projection (RP) concept for dimensionality reduction. Furthermore, the classification is performed by a neuro-fuzzy classifier. Such a model can be easily implemented on portable systems for practical applications in both health monitoring and diagnostic...
Recent years have shown an alarmous increase in rain fall induced landslides. This has facilitated the need for having a monitoring system to predict the landslides which could eventually reduce the loss of human life. We have developed and deployed a Wireless Sensor Network to monitor rainfall induced landslide, in Munnar, South India. A successful landslide warning was issued in June 2009 using...

In the current decade, substantial growth in number of wireless sensor network deployments to sense a wide array of data ranging from environmental to healthcare is observed. As these WSNs are designed with the goal to serve their own organisation without futuristic idea of sharing the data with others, their architectures pose a limitation to the purpose of collaboration. A design is presented in...
Many cross-layer architectures have been proposed in recent years. Most of them extend the traditional protocol stack in order to keep compatibility, which add complexity by incorporating many components. And very few are revolutionary, which break the stack structure to pursue good performance at the cost of compatibility. In this paper, we propose a network architecture with a layering and non-stack...
In this paper, we proposes a cognitive cross-layer architecture for the cognitive ad hoc networks, where each node in the networks can sense and learn from wireless environment, network environment and user's requirements, and then it will respond the changes of environment by adapting system parameters and network services based on the learned results. In this way, it can provide the end-to-end goals...
