Along with the growing demand of Wireless Sensor network applications, services are also increasing to fulfill the requirements of applications for different aspects. Therefore best service selection for the applications is difficult for the untrained (Non parametric) users. To select the best service, various criteria will be as per the requirements of WSNs applications. As per the criteria service...
Augmented reality (AR) is a promising technology for building applications in an Internet of Things (IoT) environment, utilized for visualizing information provided by IoT devices. In this paper, we enable Web-based mobile AR applications with mobile agents in a resource-oriented IoT system architecture. We present an adaptable mobile agent composition that contains the data representation logic and...
Due to advances in wireless network technology, new applications are designed in medical and health care domain. Medical personnel efficiency has increased by using these new tools and applications. Patient of young and elderly people as well as smart houses equipped with sensors and information technologies are subject to discussion. Patients wear sensors to monitor vital signs reported in real-time...
This work addresses networked embedded systems enabling the seamless interconnection of smart building automations to the Internet and their abstractions as web services. In our approach, such abstractions are used to primarily create a flexible, holistic and scalable system and allow external end-users to compose and run their own smart/green building automation application services on top of this...
With research on Wireless Sensor Networks (WSNs) becoming more and more mature in the past five years, researchers from universities all over the world have set up testbeds of wireless sensor networks, in most cases to test and evaluate the real-world behavior of developed WSN protocol mechanisms. Although these testbeds differ heavily in the employed sensor node types and the general architectural...
The application of WSN is emerging as a new trend in different sphere of modern society. However due to the advancement of SWE, discovering sensor web registry services throughout heterogeneous environments is becoming a challenging task and raises several concerns like performance, reliability, and robustness. Many approaches and frameworks have been proposed to discover the sensor web registry services...
With the rapidly growth of wireless sensor networks (WSN), more and more services provide people up-to-date information such as weather forecast, earthquake reports, fire alarm, even for the surveillance system, and so on. The raw data are usually hard to be understood by users. We had proposed an innovated sensor observation service with web-based and GIS-based architecture, which is named WSN Application...
Networking is the practice of communicating and data sharing among devices, through wired or wireless network, and it is playing a pivotal role in our daily life. In other words, Networking is essential for information exchange. However, along with all the benefits from networking technologies, comes various of new challenges, such as network management, network discovery and selection, etc. Due to...
In this work, we present a concrete framework, based on web services-oriented architecture, for integrating small programmable objects in the web of things. Functionality and data gathered by the Small Programmable Objects (SPO) are exposed using Web Services. Based on this, by exploiting XML encoding, SPO can be comprehensible by any web application. The architecture proposed is focused in providing...
This paper presents a middleware for Wireless Sensor Networks that uses a set of technical statements, such as patterns and styles, in order to achieve flexibility, autonomy and adaptation. The middleware exposes the functionality of the network as Semantic Web Services, so that applications can access its functionality through Web Services. The Service-oriented architecture is used as a means of...
Thanks to the coordinated infrastructure composed by a distributed collection of different resources, sensor webs currently represent a very effective solution to earth observation. These global entities are able to coordinate networks of heterogeneous sensing platform, such as spacecrafts, airborne instruments, or ground-based devices. In the framework of technologies operating at local level, wireless...
This paper deals with a lightweight implementation of the eXtensible Messaging and Presence Protocol (XMPP) protocol for the Contiki operating system, offering a standardized, open, web-service like architecture, as opposed to existing technologies which lack proper open architecture. To achieve our objective, our implementation is based on the Internet Protocol version 6 (IPv6) and XMPP. Until recently...
Characteristics of wireless sensor networks (WSNs) make their management different from traditional networks. With service oriented concepts having been implemented in WSNs, this paper investigates service oriented management of heterogeneous WSNs. A services oriented management architecture for heterogeneous WSNs is proposed in order to make better use of network management business processes from...
