Answer 1

In a ZigBee tree topology, if a child loses it connection with its FFD, it becomes a(n)

It becomes Wireless Sensor Networks (WSN) wireless sensor networks (WSNs) emerge as an active research area in which challenging topics involve energy consumption, routing algorithms, selection of sensors location according to a given premise, robustness, efficiency, and so forth. Despite the open problems in WSNs, there are already a high number of applications available. In all cases for the design of any application, one of the main objectives is to keep the WSN alive and functional as long as possible.

Which of the following is true about the OSI model and IEEE 802?

Option (b) is correct, because It handles error-free delivery and controls the flow of frames between sender and receiver across a network.
