  1. PERFORMANCE ANALYSIS OF AODV, OLSR, DSR AND GRP ROUTING PROTOCOL OFMOBILE ADHOC NETWORK – A REVIEW IJCSMC, Vol. 2, Issue. 6, June 2013, pg.359 – 362 SuchitaBaxla, Prof. Rajesh Nema Department of Electronics & Communication, NRI College, Bhopal, M.P, India Department of Electronics & Communication, NRI College, Bhopal, M.P, India Suchi_baxla@rediffmail.com; Rajeshnema2010@rediffmail.com Speaker: Arak Date : 2014-1-23

  2. Outline • Introduction • Reactive routing protocol • AODV, DSR • Proactive routing protocol • OLSR • Hybrid routing protocol • GRP • Conclusion • References

  3. Introduction • MANET(Mobile Ad hoc Network) • An ad hoc or temporary wireless network • There are no dedicated routers, servers, access points, base stations and cables • Transmission • Directly (transmission range) • Forward (otherwise) • Every node has to function as a router

  4. Introduction Ad hoc Routing Protocols • Classification of routing protocols • By routing strategy • table-driven (Proactive) • on demand or source initiated (Reactive) • By network structure • flat routing • hierarchical routing • geographic position assisted routing • Most popular methods • proactive routing • reactive routing • hybrid routing Hybrid Routing Flat Routing Reactive Proactive DSDV OLSR WRP FSR AODV DSR TORA ZRP CEDAR ZHLS DDR

  5. Reactive routing protocol • Ad Hoc on-Demand Distance Vector Routing (AODV) • Constantly sending “hello messages” • Gone down or moved out of reach • RREQ, RREP messages • Dynamic Source Routing (DSR) • Pure on demand protocol • Both route discovery and maintenance are on demand • Routing overhead traffic scales to actual needed size

  6. Proactive routing protocol • Optimized Link State Routing (OLSR) • Pure link state protocol • Periodic control message • Suitable for large and dense ad hoc network • MPRs(Multipoint Relays) • MPR nodes are selected as intermediate nodes in the path

  7. Hybrid routing protocol • GRP (Gathering-based Routing Protocol) • short transfer delay and small overheads • But complexity and overhead required

  8. Table 1: Comparison between the three categories of routing protocols

  9. Conclusion • presented and discussed the routing protocols in mobile ad hoc networks and provided comparisons between them • Which one is the best? • Each routing protocol has unique features • still many challenges facing wireless ad hoc networks • Power consumption • Speed • each protocol has their own merits and demerits and is well suited for certain situations • it is not clear that any particular algorithm or class of algorithm is the best for all scenarios

  10. References • Performance analysis of AODV, OLSR, DSR and GRP routing protocol of mobile Ad hoc network – a review • Optimized Link State Routing Protocol for Ad Hoc Networks
