As nodes appear and disappear in a Wireless Sensor Network (WSN), communication protocols acting in the data link, network and transport layers adapt dynamically to the new network structure. We present an extension of the dynamic nature of WSNs to the web via an adaptive communication protocol called the adaptive Sensor Web Language (SWL). Adaptive SWL provides a web application with a reliable mechanism...
With the development of sensor, wireless mobile communication, embedded system and cloud computing, the technologies of Internet of Things have been widely used in logistics, Smart Meter, public security, intelligent building and so on. Because of its huge market prospects, Internet of Things has been paid close attention by several governments all over the world, which is regarded as the third wave...
This paper discusses an embedded access gateway, which takes OMAP3530 as the center core and is built upon the embedded Linux 2.6 operating system. Based on the character and advantage of 3G and ZigBee, this article advances the solution scheme of the wireless home gateway. Mainly analyzes the software design of the gateway, including the way to realize the communication between the gateway and 3G...
A novel communication platform is presented, which helps in the monitoring and deployment of distributed wireless networks. Its major part is based on distributed embedded web servers connected to RF-communication heads. The web servers act as distributed communication hubs and exchange data via XML-feeds with web2.0-capable clients. The first implementations are concentrating on the monitoring direction,...
Today the construction of wireless sensing systems requires the use of rather high-priced pieces of hardware and the assembly of these hardware parts (wireless transmission core, sensor module, gateway device), as well as the implementation of the according software (sensor mote software, gateway software, end user software). This makes overall development and the thereby resulting product costly...
The NIST-supported IEEE 1451 set of standards is being developed to unify diverse standards by providing a base protocol which allows interoperability between sensor/actuator networks and busses. A key feature of the IEEE 1451 standard is that the data (and meta-data or TEDS) of all transducers are communicated on the Internet with the same format, independent of the sensor physical layer (wired or...
This paper provides a novel method to access ZigBee based wireless sensor networks (WSN) from the Internet using web service approach. We designed a novel gateway between the WSN and the Internet mainly for the scenario of home and building automation. With the improvement of the traditional gateway, the users on the Internet can access the data of the sensor networks flexibly via web services. Each...
In this paper, we propose a secure embedded gateway system for a wireless sensor network that provides secure wireless and wire communication channels for wireless sensor nodes and applications in the Internet, respectively. It also has security functions such as key management, access control and secure wireless network configuration for wireless sensor nodes and secure query process for its applications...
