Connecting wireless sensor networks (WSNs) to the Internet using the traditional IPV6 protocol is a significant challenge due to the short frame length of the WSN medium access layer and large IPV6 and UDP headers. Therefore, the Internet Engineering Task Force (IETF) recently formulated an encoding format (LoWPAN IPHC) to compress the IPV6 header from several bytes to several bits. A context table...
End-to-end communications with Internet-integrated sensing devices will contribute to the enabling of many of the envisioned IoT applications. Communication technologies with this purpose are currently being designed based on the 6LoWPAN adaptation layer, and of particular interest is CoAP (Constrained Application Protocol). The support of security in end-to-end CoAP communications with mobile Internet-integrated...
Internet of Things (IoT) is the technique to connect each and everything to Internet, and it provides anything at anytime regardless of where the thing is located. If we connect devices in this way, by 2020, billions of devices will get connected to the Internet. The current trends shows that the deployment of sensors and IoT paradigm growing in a rapid pace. This shows that the next information revolution...
Online social networks have long been studied by researchers to unearth the common patters of socializing among human beings. Recently, there is considerable interest in Internet-of-Things which is an interaction of smart physical objects augmented with sensing devices. However, there is hardly any research on intra-smart object interactions and interactions among smart physical objects and humans...
Wireless Sensor Networks (WSN) are already enabling and enhancing a large number of pervasive computing applications in homes, offices, production facilities, and vehicles, just to name a few. Despite the tremendous evolution achieved in terms of robustness, reliability, maintenance costs, interoperability and other areas, WSN are still difficult to program. This work addresses specifically the case...
Typical sensor networks are formed by low-end, battery operated devices, which rely on low-energy communication technologies, such as Bluetooth, Zigbee and ANT+, due to their energy efficiency. On the other hand, sensor networks increasingly need to be connected to the Internet, which implies adaptations of the TCP/IP stack to fit such wireless technologies. These adaptations bring additional complexity...
In this paper, a data acquisition and integration platform for internet of things is proposed. The platform is developed under a cloud computing environment using context-oriented approaches. It collects sensor data from different types of sensor devices, including such as RFID, ZigBee sensors, GPS devices, temperature sensors, humidity sensors, luminance sensors, etc. First we are devoted to the...
This paper presents a framework for the virtualization of real world objects and the cognitive management of their virtual counterparts. The framework consists of three levels of functionality and each level comprises cognitive entities that provide the means for self-management and learning, allowing for smart, flexible applications and objects. The presented framework enables the abstraction of...
This visionary paper presents the Internet of Things paradigm in terms of interdependent dynamic dimensions of objects and their properties. Given that in its current state Internet of Things (IoT) has been viewed as a paradigm based on hierarchical distribution of objects, evaluation of the dynamic nature of the hierarchical structures faces challenges in its evaluation and analysis. Within this...
Internet of Things (IoT) is an inter-network to which innumerable smart devices are connected, and eventually integrate the objective world with the information world. IoT is able to greatly improve the efficiency of productive process and promote the harmony between man-made and natural environments. Due to the variability and complexity of the future wireless network environment and the scarcity...
The development of dependable context-aware applications represents a major challenge to software engineers of contemporary systems. In this context, this position paper proposes the definition of a Context-Aware Exception Handling Mechanism to be incorporated into the Mid Sensor Net, a middleware of multi-tier services for Wireless Sensor Networks(WSNs) that provides a expressive and flexible mechanism...
The paper presents the issues on the role of wireless access networks to support the kind of information exchange and interactions involved in the evolving social networks. The author discusses several requirements that the wireless access networks and social networking needs to address such as the communication infrastructure, distributed and informal trusts, environment interactions, body interactions,...
The development of information and communication technology during the past 20 years is characterised through the continued technical evolution. These technical developments raise the possibility of new applications and application areas. It is important for the acceptance of new technologies, that new applications create additional value, use the advantages of basic technologies and are adapted to...
This paper describes the core of an spontaneous service provision framework offering general functionality based on objects in Internet of Things. The framework supports sensor, wireless network and end system based on services and service features. The framework is more generic than traditional hierarchical sensor and actuator networks framework. It supports grids and spontaneous service provision...
Context-aware services, such as location-based services, augmented reality applications, smart enterprise or assisted living applications, constitute a cornerstone of the Future Internet. One important part of such applications is context information that describes the situation in which users consume the service. While earlier context referred mainly to location information provided by network operators,...
Telecommunications and information technology rapidly migrate towards the Future Internet (FI) era, which is characterized by powerful and complex network infrastructures, advanced applications, services and content, efficient power management as well as extensions in the business model. These features render the management of the FI world increasingly complex, compared to today. The introduction...
Sensor network ubiquitous environments may generate a lot of data including heterogeneous `raw' sensor data, low-level feature and/or trend data and higher-level context and inferenced information. This paper considers the visualization of such large, heterogeneous and complex integrated information, especially for real-time deployments facilitating rapid understanding leading to decision making....
Context-aware applications and services require ubiquitous access to context information about the users or sensors such as preferences, spatial & environmental data, available connectivity, and device capabilities. Systems for the brokering or the provisioning of context data via wireless networks do so with centralized servers or by employing protocols that do not scale well with real-time distribution...
Mobile telecommunication is evolving rapidly. People no longer only communicate with each other regardless of time and place, but also share other information that is important for tasks with which they are involved. In response to this growing trend the MediaSense framework addresses the intelligent delivery of any information to any host, anywhere, based on context-aware information regarding personal...
