What are the challenges and list the applications of wireless sensor networks?

Challenges in such WSN include high bandwidth demand, high energy consumption, quality of service (QoS) provisioning, data processing and compressing techniques, and cross-layer design.

What are different security issues in WSN?

There are several security and privacy issues associated with multi-hop routing. Some of these issues like snooping, sinkhole, tampering Sybil, clone, wormhole, spoofing, etc. affect the integrity, availability, and data confidentiality of the WSNs.

What is wireless sensor network in simple words?

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 …

What are the advantages of sensor networks?

Benefits or advantages of WSN ➨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.
