The sensor nodes can communicate among themselves using radio signals. ... The individual nodes in a wireless sensor network (WSN) are inherently resource constrained: they have limited processing speed, storage capacity, and communication bandwidth.

How do wireless sensors communicate?

A Wireless sensor network can be defined as a network of devices that can communicate the information gathered from a monitored field through wireless links. The data is forwarded through multiple nodes, and with a gateway, the data is connected to other networks like wireless Ethernet.

HOW DO sensor nodes work?

Sensor nodes in a wireless sensor network (WSN) measure environmental parameters and transmit the data back to a network gateway where it is aggregated, stored, and processed. ... Sensor nodes are usually battery operated and deployed in large numbers in difficult to reach places.
