What are the advantages and disadvantages of reactive and proactive protocols? Which one would you prefer and why? Explain with specific conditions.
What will be an ideal response?
Reactive protocols:
Advantages:
(a) The routing protocol is active only when data is required to be transmitted
between nodes.
(b) Storage of all routes not required.
Disadvantages:
(a) Latency involved when data needs to be transmitted due to non-availability
of routes.
(b) Useful Scenarios: Light traffic scenarios, where proactive protocols would
incur high overhead. Attractive for large networks.
Proactive protocols:
Advantages:
(a) Data does not face any latency due to route updates and can be sent fast.
Disadvantages:
(a) Protocol is active at all times, even when data is not being transmitted.
(b) Storage of all routes required.
Useful Scenarios: Heavy traffic scenarios. Attractive for small networks.
