Optimization of Open Shortest Path First (OSPF) routing is investigated by various preceding exploration worksby decreasing congestion as well as shortest path.The performance of the network is affected by the flooding perception in OSPF. It results in additional congestion besides further propagation time.Commonly, maximum of the nodes will conversein the Flooding in addition to Packet Forwarding mechanism. If the packet forwarding is not done then it is branded as selfish node.The throughput and performance in the communication is declined by Selfish node. Malicious nodesamend the path in addition it drops the packetwith determination. The decreases in the throughputand performance of the network as well as the escalation of the delay is occurred by malicious nodes. The decrease Flooding, Selfish nodes and malicious nodes in the network is the stimulus behind the recommended effort. This in turn increases the Throughput as well as Routing Optimization of the network.
