Comparison of Optimized Link State Routing Protocol on IPv 4 and IPv 6

Ad hoc networks are infrastructure less self organizing networks. These networks are referred to as infrastructure less because there is no physical connection between the entities of ad-hoc networks. All the entities in ad-hoc networks communicate with other entities which lie in its radio frequency range. All the mobile nodes in the network dynamically set up paths among themselves to transmit packets temporarily. A MANET is an autonomous system of mobile nodes. Nodes act as a router, client and server as well and its topology is dynamic as nodes join the network whenever there is need to transmit data and leave the network when transmission gets over. These networks do not have a Central Authority for the management of the network. In recent past, several routing protocols for MANET are being proposed. Some of the prominent and promising among them are AODV, DSR, TORA, OLSR, and DSDV.
