What is GSM in WSN?
The slave module is designed using AVR microcontroller and Zigbee module, GSM module is used for long distance communication. The GSM module uses AT commands to send the SMS on house owner mobile phone. Zigbee technology is used for wireless personal area networking.
What are wireless sensors?
A wireless sensor network (WSN) is a system designed to remotely monitor and control a specific phenomenon or event. WSNs are mostly used in agriculture to monitor environmental conditions and control irrigation (Aqeel-ur-Rehman et al. 2014).
What is GSM sensor?
(Global System for Mobile communication) is a digital mobile network. GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot. For identification of sensors, this technology has in its devices SIM cards ensuring that you have control of your assets.
What is the sensor protocol used in GSM?
Constrained Application Protocol
What is the sensor/protocol used in GSN? Explanation: Constrained Application Protocol is a specialized web transfer protocol which enables constrained devices to communicate over internet and it is required for GSN in transferring data stream. 7.
Where are wireless sensor networks used?
Such networks are used in industrial and consumer applications, such as industrial process monitoring and control and machine health monitoring. A WSN is built of “nodes” – from a few to hundreds or thousands, where each node is connected to other sensors.
How wireless sensor networks use IoT?
A wireless sensor network (WSN) is a network formed by a large number of sensor nodes where each node is equipped with a sensor to detect physical phenomena such as light, heat, pressure, etc. With the rapid technological development of sensors, WSNs will become the key technology for IoT.
Why are sensor networks different?
The topology of a wireless sensor network changes very frequently. Sensor nodes mainly use broadcast communication paradigms whereas most traditional ad hoc networks are based on point-to-point communications. Since large numbers of sensor nodes are densely deployed, neighbor nodes may be very close to each other.
What are the features of wireless sensor networks?
Characteristics of Wireless Sensor Network
- The consumption of Power limits for nodes with batteries.
- Capacity to handle node failures.
- Some mobility of nodes and Heterogeneity of nodes.
- Scalability to a large scale of distribution.
- Capability to ensure strict environmental conditions.
- Simple to use.
- Cross-layer design.
