What is Imote2?
The Imote2 is an advanced wireless sensor node platform developed at Intel Research as part of Platform X Platform X. Intel Research wiki. . It is built around the low-power PXA271 XScale CPU and also integrates an IEEE 802.15. 4 compliant radio.
What is wireless mote?
A mote is low-power computing device with a wireless radio; it is typically the size of a match box or even smaller. Using the motes, these medical sensors wirelessly transmit data to base stations, where it can be accessed by physicians and nurses.
How does wireless sensor network work?
A Wireless sensor network can be defined as a network of devices that can communicate the information gathered from a monitored field through wireless links. The data is forwarded through multiple nodes, and with a gateway, the data is connected to other networks like wireless Ethernet.
What are the types of sensor node?
In WSN, based on the sensing range and environment, the sensor nodes are classified into four groups, namely specialized sensing node, generic sensing node, high bandwidth sensing node and gateway node.
What is the size of RAM in MICA Mote type?
512 kilobytes
MICA motes come with 512 kilobytes of flash memory to hold data. They also have a 10-bit A/D converter so that sensor data can be digitized.
What is anchor node in WSN?
The aspect for many Wireless Sensor Networks (WSN) based applications is positioning. These nodes are commonly called as anchor nodes, where as other nodes with unknown location information are called non-anchor nodes or static sensor nodes.
Who invented wireless sensor network?
The first wireless network that bore any real resemblance to a modern WSN is the Sound Surveillance System (SOSUS), developed by the United States Military in the 1950s to detect and track Soviet submarines. This network used submerged acoustic sensors – hydrophones – distributed in the Atlantic and Pacific oceans.
How do sensors transmit data?
Transmitters use scientific sensors such as thermocouples, pressure transducers, flow meters, etc. to measure a specific property in a process, and then transmit the data via radio signals to a receiver. Receivers receive and interpret the wireless data.
What are the roles played by a sensor node?
The sensor node consumes power for sensing, communicating and data processing. More energy is required for data communication than any other process.
What are main components of sensor node?
A sensor node is made up of four basic components such as sensing unit, processing unit, transceiver unit and a power unit which is shown in Fig. 5. It also has application dependent additional components such as a location finding system, a power generator and a mobilizer.
What is Berkeley motes in WSN?
Berkeley Motes The mote was essentially a small form factor computer with self-contained processing, sensing and power resources. TinyOS provides a set of software components that allows applications to interact with the processor, network transceiver and the sensors.
What is the disadvantage of wireless sensor networks in transportation?
They are power hungry and connected through wires to central data processing locations [4]. Most exist- ing sensors are expensive in terms of bulky hardware and costly installation of the sensors and cables [5]. Thus installations of sensor-based traffic monitoring and control systems are very limited.
