Routing protocols in mobile ad hoc
- 1. ROUTING PROTOCOLS IN MOBILE AD- HOC NETWORKS Presented By: Meenal Vasantrao Naranje Guided By: Mr. S. Deshpande Roll No: 17102A1015
- 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.
- 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
Editor's Notes
- #17: Overhead: most routing information never used ● Scalability is a major problem
