MANET Contenders
nDSR: Dynamic Source
Routing
–Source routing protocol
–Complete path in packet header
nAODV: Ad-hoc
On-demand Distance Vector Routing
–“Hop-by-hop”
protocol
–Uses only standard IP packets, intermediate nodes maintain routing
table
nBoth are “on demand”
protocols: route information discovered only as needed
–Two phases: route discovery and route maintenance
–Difference: in DSR, source controls complete route, in AODV it only know the next
hop
nMilitary: OLSR
(Optimized Link State Routing)
–Proactive routing protocol
–Similar to OSPF, but more efficient link state updates
