Performance of OSLR in Manet using OMNETPP

The user wants the wireless network anywhere. The wireless communication devices are transmitters, receivers and various smart antennas. These smart antennas may be any kind and the number of nodes can be fixed or mobile. The term node is referred to as nodes which can move arbitrarily in any direction. The wireless mobile nodes when collected at an instant are forming a temporary network without use of any re-existing network. The Ad-hoc routing protocols have number of types which are useful during the time of connectivity to form network. Routing protocols for mobile Ad-hoc networks have to face the challenge of changing the network topology by changing the number of mobile nodes. Scalability is an open issue in all routing protocols. In this review paper, there are observations of OLSR protocol regarding the scalability comparison of the Optimized Link State Routing (OLSR) by varying the number of nodes. The simulation is done by using OMNET++ by taking end to end delay, throughput and Packet delivery ratio as performance metrics.
