Optimized Link State Routing Protocol is based on link state algorithm. OPTIMIZED LINK STATE ROUTING PROTOCOL (OLSR) There are various proactive routing protocols present for MANET like DSDV, OLSR, and WRP etc. The major drawback of proactive routing protocols includes the overhead of flooding route. One of the main advantages of this protocol is that routes are ready to use when needed. This type of protocol keeps and maintains up-to-date routing information between every pair of nodes by sending control message periodically in network. Proactive routing protocols are also known as Table-driven routing protocol uses link-state routing algorithms which floods link information about its neighbors frequently. Routing protocol is categorized on the basis of how and when route are discovered, but both select the shortest path to the destination. Security is the most important factor for any communication. Proactive operation is used when they require enough bandwidth and energy resources. Demand based operation is to decrease traffic and use bandwidth resources more efficiently. Loop-freedom is to prevent overhead created during sending information uselessly. Distributed operation means that any node can enter or leave whenever they want. Routing protocol needs to have following qualities to be effective: distributed operation, loop freedom, demand based operation, proactive operation, security and unidirectional link support. Another important issue is to keeping the routing table small, reason being increasing the routing table affects the control packets sent in the network and in turn affects large link overheads. It is necessary to reduce routing message overhead despite the increasing number of nodes. The main issue associate with the routing protocol involves being appeared and disappeared of nodes in various locations. In MANET routing protocol should be capable to handle a very large number of nodes with limited resources. Abstract :īasically, here we are comparing the various MANET Routing Protocols based on certain performance metrics like Throughput, Packet Delay Ratio, End to End Delay, Number of Packets Dropped, Jitter, etc using Ns3 Simulator. Comaparison of different types of MANET Routing Protocols using NS3 Simulator.
