Abstract
Performance of any network is based on the routing protocols. RIP, Session, OSPF and BGP are the few commonly used dynamic routing protocols used in today’s networks. Routing refers to the phenomenon of selecting the best available path to forward packets to its destination. It is a core feature for any network because the performance of the networks heavily depends upon it. In this paper we will perform comparative analysis by using Distance Vector, Link State and Session routing protocol. We will study Packet drop rate (PDR), Bandwidth / Link Utilization, End to End Delay, throughput behavior of these protocols by using network simulator 2 (ns2) for route optimization & comparative analysis to find optimal routing protocol
Highlights
Static routing has been failed to cop up with changing and growing dynamics of the network
We in this paper perform simulation based analysis by using NS2 discrete event simulator to analyze the performance of the distance vector, link state and session routing protocols
The comparison graph for distance vector, link state and session routing protocols for packet drop rate in figure 2 shows that session routing protocol has highest packet drop rate as compared to distance vector and link state routing protocol
Summary
Static routing has been failed to cop up with changing and growing dynamics of the network. There are several limitations and disadvantages of static routing as mentioned in [1]. Dynamic routing has been proven to be fault tolerant, scalable, and secure and provide high network availability and throughput. Different dynamic routing algorithms have different preferences, limitations and requirements for their smooth operation and execution within the network. We try to configure network parameters like bandwidth, delay, buffer size etc. Carefully in our network model so that network related parameters does not affect the effectiveness of one or other routing protocols in the simulation. The remainder of the paper is organized as follows: in section 2, dynamic routing protocols are reviewed.
