In this paper, four different protocols are taken, namely, Destination Sequence Distance Vector (DSDV) routing protocol, which is a proactive distance vector routing protocol; Dynamic Source Routing (DSR), which is a reactive distance vector protocol; Optimized Link State Routing Protocol (OLSR), which is a proactive link state routing protocol. First we will discuss them in brief. DSDV Routing¶ Destination-Sequenced Distance Vector (DSDV) routing protocol is a pro-active, table-driven routing protocol for MANETs developed by Charles E. Perkins and Pravin Bhagwat in 1994. These protocols can be broadly classified as (a) proactive routing protocols such as DSDV [6], FSR [7], WRP [8, 9], CGSR [10], GSR [11] etc. 0% 0% found this document useful, Mark this document as useful. time between the starting of simulation and ending of the simulation. 5.2. The routing protocols under test are DSR, DSDV, AODV, and AOMDV (Ad-hoc OnDemand Multipath Distance Vector - routing). Each node in the network maintains a routing table that has entries for each of the destinations in the network and […] DSDV is a Table driven (proactrive) protocol while DSR and AODV are typical reactive protocols. Destination-Sequenced Distance-Vector Routing (DSDV) is a table-driven routing scheme for ad hoc mobile networks based on the Bellman–Ford algorithm.It was developed by C.
