First, wireless sensor networks are typically deployed with a particular application in mind, rather than as a general platform. Second, a need for low costs and low power leads most wireless sensor nodes to have low-power microcontrollers ensuring that mechanisms such as virtual memory are either unnecessary or too expensive to implement.
A mobile wireless sensor network (MWSN) [1] can simply be defined as a wireless sensor network (WSN) in which the sensor nodes are mobile. MWSNs are a smaller, emerging field of research in contrast to their well-established predecessor.
TinyOS is an embedded, component-based operating system and platform for low-power wireless devices, such as those used in wireless sensor networks (WSNs), smartdust, ubiquitous computing, personal area networks, building automation, and smart meters. It is written in the programming language nesC, as a set of cooperating tasks and processes.
A sensor node, also known as a mote (chiefly in North America), is a node in a sensor network that is capable of performing some processing [1], gathering sensory information and communicating with other connected nodes in the network. A mote is a node but a node is not always a mote.
Wireless sensor network is a new paradigm in designing fault tolerant mission critical systems, to enable varied applications like threat detection, environmental monitoring, traditional sensing and actuation and much more. It is an emerging area of inter-disciplinary research between people in the electrical engineering, computer science, and ...
Some of these technologies include standards such as ANT UWB, Bluetooth, Zigbee, and Wireless USB. Wireless Sensor Networks (WSN / WSAN) are, generically, networks of low-power, low-cost devices that interconnect wirelessly to collect, exchange, and sometimes act-on data collected from their physical environments - "sensor networks". Nodes ...
ERIKA Enterprise is a real-time operating system (RTOS) kernel for embedded systems, which is OSEK/VDX certified. It is free and open source software released under a GNU General Public License (GPL).
Sensor web is a type of sensor network that heavily utilizes the World Wide Web and is especially suited for environmental monitoring. [1] [2] [3] OGC's Sensor Web Enablement (SWE) framework defines a suite of web service interfaces and communication protocols abstracting from the heterogeneity of sensor (network) communication.
