What is Rreq packet?
When a node has some data to send to a destination and it does not have the valid routing table entry, it generates a Route Request (RREQ) packet and broadcasts it to all its neighbors. When an intermediate node receives this RREQ, it searches its local routing table for a valid route to the requested destination.
What is Rrep packet?
The RREP packet contains for source and destination addresses, destination sequence. number, hop count, and lifetime. The source and destination correspond to the same source and destination of. the RREQ packet. Each node that receives the RREP packet updates its routing table and retransmits the packet.
What are the 3 nodes of Aodv?
On receipt of the three AODV messages: RREQ, RREP and RERR, the nodes update the next hop, sequence number and the hop counts of their routes in such a way as to satisfy the partial order constraint mentioned above [7].
What are the fields for Rrep?
It contains type field, source address field, destination field, unique identification number field, hop field, max-cost field, cost (cumulative cost) field and path field. . …

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.
What is DSR protocol?
Dynamic source routing protocol (DSR) is an on-demand protocol designed to restrict the bandwidth consumed by control packets in ad hoc wireless networks by eliminating the periodic table-update messages required in the table-driven approach. Consider a source node that does not have a route to the destination.
What is protocol in router?
A routing protocol specifies how routers communicate with each other to distribute information that enables them to select routes between nodes on a computer network. Routing algorithms determine the specific choice of route. Each router has a prior knowledge only of networks attached to it directly.
What is Tora in mobile computing?
The Temporally Ordered Routing Algorithm (TORA) is an algorithm for routing data across Wireless Mesh Networks or Mobile ad hoc networks. It was developed by Vincent Park and Scott Corson at the University of Maryland and the Naval Research Laboratory.
