Optimization Link Sate Routing Analysis with Destination Sequenced Distance Vector for MANET

Every node functions as a router, finding and maintaining routes to other nodes in the network to let them know about their benefits. However, security, energy, and transmission are still disadvantages. In a mobile setting, routing is handled via a variety of protocols. Routing protocol performance is a critical issue due to its extremely dynamic nature. The two well-known protocols that will be the subject of this study are the Optimized Link State Routing (OLSR) and Destination Sequenced Distance Vector (DSDV) protocols. When the routing protocols are built using NS2.34, the simulation result demonstrates the best routing protocol that offers the best performance. A notable attack in this study is the node isolation attack, which is a denial-of-service (DDOS) attack against the Optimized Link State Routing protocol (OLSR). Two ad hoc routing protocols are compared in the simulation: destination-sequenced distance vector and optimal link state routing methods. We give simulation-based comparison and performance analysis on multiple factors, including throughput, normalized routing overhead, and average end-to-end delay.
