“…The implementation is developed using the EXIP framework, and consists of an experimental Java browser running on a laptop PC that connects to a wireless sensor device (Mulle version 3.2 [Eliasson et al 2008]) over Bluetooth. The laptop user can navigate to the device Web interface using mDNS/DNS-SD or CoAP built-in discovery capabilitiesmulticast service discovery [Shelby et al 2013a], or CoRE Resource Directory [Shelby et al 2013b].…”

Developing and deploying Web applications on networked embedded devices is often seen as a way to reduce the development cost and time to market for new target platforms. However, the size of the messages and the processing requirements of today's Web protocols, such as HTTP and XML, are challenging for the most resource-constrained class of devices that could also benefit from Web connectivity.New Web protocols using binary representations have been proposed for addressing this issue. Constrained Application Protocol (CoAP) reduces the bandwidth and processing requirements compared to HTTP while preserving the core concepts of the Web architecture. Similarly, Efficient XML Interchange (EXI) format has been standardized for reducing the size and processing time for XML structured information. Nevertheless, the adoption of these technologies is lagging behind due to lack of support from Web browsers and current Web development toolkits.Motivated by these problems, this article presents the design and implementation techniques for the EXIP framework for embedded Web development. The framework consists of a highly efficient EXI processor, a tool for EXI data binding based on templates, and a CoAP/EXI/XHTML Web page engine. A prototype implementation of the EXI processor is herein presented and evaluated. It can be applied to Web browsers or thin server platforms using XHTML and Web services for supporting human-machine interactions in the Internet of Things.This article contains four major results: (1) theoretical and practical evaluation of the use of binary protocols for embedded Web programming; (2) a novel method for generation of EXI grammars based on XML Schema definitions; (3) an algorithm for grammar concatenation that produces normalized EXI grammars directly, and hence reduces the number of iterations during grammar generation; (4) an algorithm for efficient representation of possible deviations from the XML schema.

“…Bluetooth is also a proprietary protocol, but it allows a bidirectional and point-to-point interaction, but needs of a pairing process to enable that communication link. Bluetooth has also been used to form wireless sensor networks using TCP/IP [ 22 ].…”

Information and Communication Technologies (ICTs) continue to overcome many of the challenges related to wireless sensor monitoring, such as for example the design of smarter embedded processors, the improvement of the network architectures, the development of efficient communication protocols or the maximization of the life cycle autonomy. This work tries to improve the communication link of the data transmission in wireless sensor monitoring. The upstream communication link is usually based on standard IP technologies, but the downstream side is always masked with the proprietary protocols used for the wireless link (like ZigBee, Bluetooth, RFID, etc.). This work presents a novel solution (WebTag) for a direct IP based access to a sensor tag over the Near Field Communication (NFC) technology for secure applications. WebTag allows a direct web access to the sensor tag by means of a standard web browser, it reads the sensor data, configures the sampling rate and implements IP based security policies. It is, definitely, a new step towards the evolution of the Internet of Things paradigm.

Abstract-This paper discusses results from real-life tests with intelligent road marking units (RMU), placed on the surface of a highway in northern Sweden, to monitor passing vehicles and road properties, as well as making the information available through a wireless sensor network. Wireless sensor networks are starting to gain interest in the area of cooperative safety and efficiency in transport as they can contribute to the reduction of accidents and emissions as well as enhanced driver experiences. Intelligent road markings are another key element for the creation of intelligent transport systems, complementing road side units, devices placed near a road equipped with highperformance computational platforms and long range communication capabilities. This paper shows that RMUs are feasible from the perspectives of low-power consumption, durability, and sensing performance.
