Sari. destination sequenced distance vector (DSDV) protocol [7] is an adaptation of the classical Bellman-Ford [11] routing protocols. i.e. dsdv routing protocol is because not require a lifetime of the source ip address auto configuration data to have to a reference. These protocols utilize the flooding technique to find routes. It actually extends the distance vector routing protocol of the wired networks as the name suggests. After that their results are compared based on throughput and number of packets dropped during communication. Department of Electrical Engineering, Universitas Riau . The AODV protocol is tested from the reactive protocol group, while the DSDV routing protocol is taken from the proactive group. DSDV is a Table driven (proactrive) protocol while DSR and AODV are typical reactive protocols. Destination sequenced distance vector routing protocol (DSDV) Modi cation of the Bellman-Ford algorithm where each node maintains: the shortest path to destination; the rst node on this shortest path. Destination Sequenced Distance Vector (DSDV) is a hop-by-hop vector routing protocol requiring each node to periodically broadcast routing updates. Protocol Used In MANITs A. Ad-hoc On-demand distance vector (AODV) is another variant of classical distance vector routing algorithm, based on DSDV and DSR .AODV (Ad Hoc On-Demand Distance Vector Routing) It is a reactive routing protocol, meaning that it establishes a route to a destination only on demand. Table-Driven/Proactive MANET Routing Protocol: DSDV Destination Sequenced Distance Vector (DSDV) Protocol Why do we need a new protocol … It does not cause any packet to be forwarded, and is synchronous.
