The two main classes of adaptive routing protocols in the internet: distance vector and link state. This paper presents the comparison between distance vector and link state. It also outlines the pros and cons of RIP and OSPF protocols and a performance analysis with some possible enhancement is presented. Network Simulator (NS2) is used to obtain the performance results of the two classes using different metrics such as throughput, packet delay and packet loss. Results of the simulation show that OSPF has a better performance than RIP in terms of average throughput and packet delay in different network sizes, while RIP is better than OSPF in terms of number of packet loss in large networks.
