10. Proactive vs Reactive Routing
Proactive Routing Protocols (DSDV, OLSR)
+ Routes to all reachable nodes in the network available.
+ Minimal initial delay for application.
- Larger signalling traffic and power consumption.
Reactive Routing Protocols (DSR, CBR etc)
+ Smaller signalling traffic and power consumption.
- A long delay for application when no route to the destination available

11. Routing Protocols: Overview
Proactive protocols
Determine routes independent of traffic pattern
Traditional link-state and distance-vector routing protocols are proactive
Examples:
DSDV (Dynamic sequenced distance-vector)
OLSR (Optimized Link State Routing)
Reactive protocols
Maintain routes only if needed
DSR (Dynamic source routing)
AODV (on-demand distance vector)
Hybrid protocols
Example: Zone Routing Protocol (intra-zone: proactive; inter-zone: on-demand)
