Is WSN same as IoT?
WSN as a Subset of IoT IoT exists at a higher level then WSN. In other words, WSN is often a technology used within an IoT system. A large collection of sensors, as in a mesh network, can be used to individually gather data and send data through a router to the internet in an IoT system.
What is base station in WSN?
The base stations are one or more components of the WSN with much more computational, energy and communication resources. They act as a gateway between sensor nodes and the end user as they typically forward data from the WSN on to a server.
What are the challenges of WSN?
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.
How are base stations used in the IoT?
A base station is designed to receive all data transmitted from the sensing node and display it through GUI available at the personal computer, with the possibility of controlling ON and OFF appliances according to consumer requirements; All of these readings will be stored at database for analysis.
How are base stations similar to sensor nodes?
Similar to sensor nodes, even base stations can be either static or mobile. A static base station has a fixed position usually close to the sensing region. A mobile base station moves around the sensing region so that the load of sensor nodes is balanced. In a single-hop WSN, the sensor nodes are directly connected to the base station.
How is a mobile base station different from a multi-hop WSN?
A mobile base station moves around the sensing region so that the load of sensor nodes is balanced. In a single-hop WSN, the sensor nodes are directly connected to the base station. In case of multi-hop WSN, peer nodes and cluster heads are used to relay the data so that energy consumption is reduced.
What can WSNS be used for in the real world?
In recent years, WSNs is used for environmental monitoring, health monitoring and industrial monitoring as a means of reducing the energy consumption. WSNs are also highly flexible and supports power management using Web services and middleware technologies.
