2) Network Layer: The Network layer can also be called
‘Transmission Layer’. This layer securely transfers the
information from sensor devices to the information
processing system. The transmission medium can be
wired or wireless and technology can be 3G, UMTS,
Wifi, Bluetooth, infrared, ZigBee, etc depending upon
the sensor devices. Thus, the Network layer transfers the
information from Perception layer to Middleware layer.
