What is meant by AODV and explain about AODV routing protocol?

AODV (Ad-hoc On-demand Distance Vector)[7] is a loop-free routing protocol for ad-hoc networks. It is designed to be self-starting in an environment of mobile nodes, withstanding a variety of network behaviors such as node mobility, link failures and packet losses.

What problems are addressed using destination sequence number AODV routing protocol?

It uses destination sequence numbers to ensure loop freedom at all times (even in the face of anomalous delivery of routing control messages), solving problems (such as “counting to infinity”) associated with classical distance vector protocols.

What is Rreq?

The full form of RREQ is Route Request. It’s used on Computing ,Networking in Worldwide. When one node needs to send a message to another node for which it does not already have a route it broadcasts a Route Request (RREQ) message. By sending RREQ the node is asking the network how to get to the destination.

What is AODV in mobile computing?

An Ad Hoc On-Demand Distance Vector (AODV) is a routing protocol designed for wireless and mobile ad hoc networks. This protocol establishes routes to destinations on demand and supports both unicast and multicast routing.

What is Rreq and Rrep?

RREQ = Route Request message, RREP = Route Reply.

What are the steps to create shortest path in LSR?

Discover its neighbors and build its neighbor table. Measure the cost (delay, bandwidth, etc) to each of its neighbors. Construct and send a routing update telling all it has learned to all routers in the network. Apply the Dijkstra algorithm to construct the shortest path to all possible destinations.

What is the purpose of Rreq and Rrep packets in routing?

The RREQ packet is forwarded by intermediate nodes which also create a reverse route from the destination. When the request reaches a node with a route to the destination node it also creates a Route Reply (RREP) which contains the number of hops that are required to reach the destination.
