July 14, 2021 By admin

This article lists 100+ Wireless Sensor Network MCQs for engineering students. All the Wireless Sensor Network Questions & Answers given below include a hint and wherever possible link to the relevant topic. This is helpful for the users who are preparing for their exams, interviews, or professionals who would like to brush up their fundamentals on the Wireless Sensor Network topic.

Wireless Sensor Network is also represented as “WSN” and it is a group of dedicated sensors that are spatially dispersed to records, monitors physical environmental parameters, and organizes that data at a central location. WSN measures physical parameters such as temperature, pressure, wind, humidity, and many more.

This network comprises base stations and nodes at different locations, that communicate wirelessly. WSN for radio communication can be implemented in 4 topologies namely – Star type topology, tree-type topology, and Mesh type topology.

Depending on the physical environment, WSN is classified into 5 types namely underground type WSN, terrestrial type WSN, underwater type WSN, multimedia type WSN, and mobile type WSN. The advantage of WSN is to avoid the need for wiring, it is a flexible technology, and can be integrated on a large scale.
