routing protocol

A formula used by routers to determine the appropriate path onto which data should be forwarded. The routing protocol also specifies how routers report changes and share information with the other routers in the network that they can reach. A routing protocol allows the network to dynamically adjust to changing conditions, otherwise all routing decisions have to be predetermined and remain static. See content-addressable memory, router, routing table, RIP, OSPF, IGRP, EGP and BGP.


A Routing Table
This is a simple example of a routing table, showing how packets are directed out the appropriate port.

DSDV is the proactive routing protocol, the theory of this type protocols is that each mobile node establishes and maintains a complete routing table which contains the route to each node, it can rapidly reflect the network topology, the delay of this type is smaller, but the routing overhead is larger, the efficiency of protocol is lower; DSR and AODV are the reactive routing protocols, the theory of this type's protocols is that each node do not maintain any information of the routing in advance, only when sending data to the destination node, the source node launches the routing searching process in the network to search and establish the corresponding routing, thus this way save some unnecessary routing overhead, but increases the packet transmission delay.
