What is WSN and its applications?

Currently, WSN (Wireless Sensor Network) is the most standard services employed in commercial and industrial applications, because of its technical development in a processor, communication, and low-power usage of embedded computing devices.

What is Wireless Sensor Network and its classification?

WSNs stands for Wireless Sensor Networks can be defined as a self-configured and infrastructure-less wireless network to observe physical or environmental conditions, like temperature, pressure, motion, sound, vibration, or pollutants, and to directly pass their data or information through the network to a sink which …

What are the features of wireless sensor networks?

Wireless sensor networks are composed of low-energy, small-size, and low-range unattended sensor nodes. Recently, it has been observed that by periodically turning on and off the sensing and communication capabilities of sensor nodes, we can significantly reduce the active time and thus prolong network lifetime.

What is the limitation of wireless sensor networks?

One of the biggest disadvantages of large scale wireless sensor networks lies on the complexity of logistics involving selective replacement of sensors that have ran out of energy. The lower speed compared to wired network.

What communication is used in WSN?

Through wireless sensor networks (WSN), we can acquire the various interesting event information around sensor nodes through multihop communications. In WSN, there are two types of applications, that is, event or query based.

What are the limitations of WSN?

What are the protocols in wireless sensor networks?

Dynamic source routing (DSR) is a routing protocol used in wireless sensor networks developed at CMU in 1996. Dynamic source routing can be reactive or on demand.

What are the advantages of sensor network?

➨It is scalable and hence can accommodate any new nodes or devices at any time. ➨It is flexible and hence open to physical partitions. ➨All the WSN nodes can be accessed through centralized montoring system. ➨As it is wireless in nature, it does not require wires or cables.

What is wireless sensor network discuss the benefits and limitations of wireless sensor networks?

Wireless Sensor Networks (WSNs) can be defined as a self-configured and infrastructure-less wireless networks to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a main location or sink where …
