Routing Protocols for MANETS Unicast-Routing Protocol for MANET (Topology-based) CBRP Table-Driven/ Proactive Hybrid On-Demand-driven/Reactive Clusterbased/ Hierarchical Distance- Vector Link- State ZRP DSR AODV TORA LANMAR CEDAR DSDV OLSR TBRPF FSR STAR MANET: Mobile Ad hoc Network (IETF working group)

  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. 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 Examples: DSR (Dynamic source routing) AODV (on-demand distance vector) Hybrid protocols Example: Zone Routing Protocol (intra-zone: proactive; inter-zone: on-demand) Routing Protocols: Overview
