3.  Advantages:
Ad-hoc networks have several advantages
over the traditional networks, like:
 Ad-hoc networks can have more flexibility.
 It is better in mobility.
 It can be turn up and turn down in a very short
time.
 It can be more economical.
 It considered a robust network because of its non-
hierarchical
 distributed control and management mechanisms.

5. AODV(AD-HOC ON-DEMAND DISTANCE
VECTOR)

7. ADVANTAGES AND DISADVANTAGES
 Advantages:
 Less overhead network
 Because it is reactive in nature, AODV can handle
highly dynamic behavior
 The connection setup delay is lower
 Disadvantages:
 Due to on demand traffic is major issue due to RREQ
and RREP packet
 It is difficult to major expiry time of a route if no data
packet is transferred
 Intermediate node can lead to inconsistent route if the
source sequence number is very old

8. DSR (DYNAMIC SOURCE ROUTING)
 Reactive or On Demand
 Route discovery cycle used for route finding – on
Demand
 Maintenance of active routes
 No periodic activity of any kind – Hello Messages
in AODV
 Utilizes source routing (entire route is part of the
header)
 Use of caches to store routes

12. ROUTE REPLY IN DSR

13. ADVANTAGES AND DISADVANTAGES
 Advantages:
 Route maintain only between nodes who need to
communicate. Reduce overhead of routing
maintenance.
 Route caching reduce route discovery overhead.
 Single route may yields many route to the destination.
 Disadvantages:
 Packet header grows with the route length due to
source routing.
 Route reply storm problem.

14. DSDV(DESTINATION-SEQUENCED DISTANCE-
VECTOR)
 It is proactive protocol
 Make use of bellman ford algorithm to reach
destination.

16. ADVANTAGES AND DISADVANTAGES
 Advantages:
 Path Selection: DSDV maintains only the best path instead
of maintaining multiple paths to every destination. With this,
the amount of space in routing table is reduced.
 Simple (almost like Distance Vector)
 No latency caused by route discovery
 Disadvantages:
 Overhead: most routing information never used
 It is difficult to determine a time delay for the advertisement
of routes
 Traffic Congestion may be an issue depending on the
updating method of routing table.
 DSDV is not used for Multi path Routing

17. ZONE ROUTING PROTOCOL
 It is Hybrid Protocol
 Local topology- proactive routing
 External zones-reactive routing
 Reduce Search Coast
 2 Zones
 Intra Zone
 Inter Zone

19. ADVANTAGES AND DISADVANTAGES
 Advantages:
 When transmission is required then broadcast is
initiated.
 Reactive and proactive both types of routing is possible
 Disadvantages:
 Lack of hierarchy format
 Complex as zone wise routing information maintenance
is difficult.
 Zones are overlapped
