What is the layered architecture of the Internet? In a
wireless network, describe how each layer would be different
from a wired network?
Answer / guest
5- Layer architecture of the Internet:
Application (Layer 5)
Transport (Layer 4)
Network (Layer 3)
Data Link (Layer 2)
Physical (Layer 1)
Differences between wireless network and wired network:
(1) Wired network uses wires (e.g., twisted pair, coax,
fiber optic) as transmission
media in physical layer. Wireless network uses air waves,
which requires different coding,
modulation schemes.
(2) Interference and collision is much more severe in
wireless networks. Data link
layer in wireless network uses different techniques to avoid
collision and make sure data
was received.
(3) Wireless network needs to deal with device location and
handover in network
layer. In wireless ad hoc networks, routing can be different
than wired networks.
(4) No big difference between wireless and wired network in
transport layer.
(5) Application layer is unaware of the physical aspects of
the network. Application
layer in wired network supports services like FTP, SMTP etc.
One can also take the
physical layer characteristics into account when writing an
application.
