Furthermore, what is nodes in wireless sensor networks? Wireless Sensor Networks
Wireless sensor nodes communicate via their radio modules. Two nodes are directly connected if they can transmit/receive data to/from each other. In other words, two sensors are able to communicate directly if they are within one communication hop of each other.
